HDR

I've never much cared for HDR photos. They contradict my usual photographic approach - I'm trying to engage with and portray what is there, and it seems that a picture that is produced largely in the computer, while it may be beautiful, goes in another direction. But recently I switched to Corel photo editing software after years of using Lightroom and Photoshop, and my new program, Paintshop Pro has an HDR option,  so why not try it out? It made the photograph above, out of this:
And I realised, that not only did the HDR shot look better than the orignal, but it expressed more accurately what it was I saw on the headland at Karitane back in late December 2011.

So for the last 24 hours I've been playing. There's tens of thousands of photos on my hard drive that I've never bothered with, because they are kind of nothing shots - ones that didn't quite work. There were others I've worked on over the years but never been quite satisfied with. But I've been looking again. I've been experimenting and learning. HDR won't save a bad picture, but it can help release the possibilities of some potentially OK ones, like these:



..and there's quite a few others besides. Enough to keep me occupied of a rainy Dunedin afternoon.

Interesting effects. My first reaction to the first HDR photo was that it had a 1940s WW2 feel about it. Why? I don't really know; perhaps it reminds me of old postcards that I have seen in second hand shops or the like. One person subjective HDR rendering is another persons subjective experience.
Kelvin Wright said…
Yes, it does look kind of old fashioned. I thought it had a kind of Christina's World feel to it.

I suppose it's not surprising. HDR is about increasing the dynamic range of photos, that is the range of levels of luminance in an image. No system of photography is able to reproduce the range accessible to the human eye, so however it is shot there is always a range of things visible to the eye which the camera obliterates either by consigning it to darkness or washing it out in whiteness. In HDR you combine the limited range of several pictures to make a picture which has the combined total range of all the contributing shots.

Its a form of photography which is easy to do but tricky to master, and my initial attempts here have got a long way to go, but I've learned a lot in the last couple of days. Once the HDR file has been made it then needs to be expressed in a photo of some sort, usually a JPEG, and the ways of doing that are pretty much infinite: a bit like a film negative being expressed in a print. Most of the HDR jpegs you see around are pretty garish and overblown, but when it is used with subtlety, the results can be astonishing.

The technology conditions us. So the limits of film defined what a colour picture should look like, and decided how we see colour and what we regard as "normal". Then digital technology more or less adopted the limits of film and made film like images because that's what they were programmed to do. HDR breaks those limits and sets (that is falsifies) what we see in a whole new range of ways. And as early film using big plate cameras had a higher dynamic range than later commercial film, the extended range of HDR does recall early film and early forays into managing HDR colour do look like early forays in controlling colour by using three different developers in big tanks in the darkroom.

One of the things I've learned is that HDR is very unforgiving. To do it well, you need very good and very large files to work with. It drives me back to the old days with a hand held meter and trying to use the zone system in Walter Logeman's darkroom. I am being forced back to long shutter speeds, careful measurement, tripods, thinking about the final image before I press the shutter, being careful with depth of field.... in other words, it is very good for me. Very good indeed.

I've taken one, and only one HDR image I'm really pleased with. It's not in this post, but I may put it up in the next few days.

The implications of the technical aspects that you talk about begs lots of philosophical questions regarding how and what we are seeing and what exactly does ultimate reality look like - Bertrand Russell covers these questions in the first chapter 'Appearance and Reality' of his very readable book 'The Problems of Philosophy'.

It is interesting that we can provide the proof that we can mimic human functions such as seeing and hearing with cameras and sound equipment but we can't proof that what each of us experiences has exactly the same tonal and colouration qualities - we can only agree on differences between things not that our consciousness is seeing the world in exactly the same way as anothers consciousness.

It is very interesting that you mention Walter Logeman's darkroom. I had recently been thinking about that darkroom, which prompted me a couple of weeks ago to find and give my 45 year old niece Shiree a black and white photo of her being held by my sister at Pages Road Christchurch when she was about 2 years old. I processed that and many more black and white photos in Walters darkroom - that must be nearly 50 years ago. I still have a few photos that came out of Walters chemical wash baths.

Although we were given permission to use the room, I remember a number of times I was there by myself feeling somewhat like a burglar and waiting for someone to open the door and ask me what the hell I was doing there.

I have a piece of old technology from those days, my Canon FTQL 35mm single lens reflex camera. A camera that took 35mm Kodak or Agfa film. A camera that has been totally eclipsed by the digital age. I have been thinking about making a nice little varnished stand for it with a name plate 'Vintage Camera Cira 1969'. Something to show the grandchildren.
Kelvin Wright said…
I too have a few old pictures developed and printed in Walter's darkroom. They're pretty crappy, but they do record a 50 years younger world and the things that caught me eye in it.

For a while, when digital SLRs first came out and I wanted one, and the family budget couldn't stretch to such things (They cost HOW much?!!?)I put my many long hours spent reading photography magazines to good use by buying and selling cameras on the internet. Between Ebay and Trademe I picked up the film cameras people were ditching in favour of pathetic little 2 megapixel Olympuses and sold them again, usually at a good profit. I got my Canon 400D in a couple of months, and in the process owned (temporarily) many wonderful cameras, including 3 or 4 FTQLs. They're a fine piece of kit. Not worth a lot now, but prices for those old well built mechanical cameras is slowly rising, and it's worth hanging onto. The trouble is, they use a battery that isn't made anymore and the nearest modern equivalent makes the light meter inaccurate.

I'm interested in how popular photography shapes our world view - what is regarded as attractive and "normal". Interested also in what people take pictures of. Themselves often. What does that say? For a while Clemency and I watched many Camino videos on Youtube. Many (most?) of them tediously consist of someone walking along filming themselves with a selfie stick. And all the while, out of focus in the background, is the wonderful Spanish countryside, and quaint villages and ancient churches being passed by.

For me, retirement has meant a leap of interest in my camera, which is a great instrument, though I would like the added clarity and the opened possibilities of a full frame sensor. (They cost HOW much?!!?)
Alden Smith said…
There is no doubt that media in all its forms and particularly its images have a huge impact on popular culture and our world view. The huge growth in international travel and holidaying and its attendant advertising seems to have "normalised" an authentic holiday as being expensive, full of opulent hotel or cruise ship suites, copious quantities of champagne and a world that is risk free; expressed in a multitude of thick brochures laden with glossy photos of the constant sunshine variety - the free spirit, do your own thing voyage, by default becomes outside the norm. The fashion industry creates similar but more odious and dark ideas of "normal" or "attractive" which play their devastation out particularly in the bodies of young women. In both these examples photography is used in a subversive way.

The question regarding what is attractive or 'normal' in other areas is an interesting one. I clearly remember Walter Logeman talking about photographs that were not of the "Chocolate Box" variety and viewing many photos he had taken that showed beauty in the ordinary and the mundane - not a revolutionary concept even then, but an important point for me at the time. Our son Nikolai constantly takes lots of the ordinary and mundane and posts them on Instagram to the point that I sometimes wish for a few of the "Chocolate Box" variety to provide balance to a point of view of the city he lives in.
I have just finished looking at his latest round of photos on Instagram (he is in Bern Switzerland at the moment) and have viewed both beautiful vistas of Switzerland along with the sweaty, gritty, visceral, photos of street life with its attendant graffiti he has shot along the way in many of Europes great cities. I find from a viewers perspective that an honest view of the world includes both photographic points of view and many more in between. As a parent I am glad he includes one selfie per session to let us know he is alive and well.

In many ways I am glad to be free of my weighty old Canon, but I do appreciate that photography enthusiasts still like to use big cameras with a variety of gear and lens in their quest for good photos.

I use a small Panasonic DMC-FT2 Lumix with a Leica lens. It slips easily into my pocket and because it is waterproof to 10m / 33 feet and has every opening protected by robust seals I can use it pretty much anywhere, especially when I go sailing without worrying about water ingress. It does have its limitations, a wide angle lens would at times be very useful and I choose adjustments on a pre-set dial for different conditions rather than an at times useful manual set up.

Good to read that retirement is aiding and abetting your interest in your camera. If I've learned anything about retirement it's that a variety of interests and the time to indulge them is a great blessing.

I would dearly love a Hasselblad camera for reasons that escape me, but maybe it has something to do with the beautiful 'Chocolate Box' images pumped out by the photographic advertising industry.
Alden Smith said…
... And by the way what exactly is a full frame sensor?
Kelvin Wright said…
Hasselblad, eh? Is it the technical excellence, or a lingering image of yourself as David Hemmings, circa 1968, with a jaunty scarf and a mop of blond hair and with a scantily clad Vanessa Redgrave disporting herself before you? Either way, they are still around, and not as unattainably expensive as they used to be. The cameras I mean. The same quality of image is now possible with the newer generation of DSLRs, and probably cheaper and easier.

I have a couple of point n shoots, including a Panasonic, but the camera in my phone is actually better. It’s only drawback is not having any choice of lens, but even that isn’t such a big deal with my latest phone as it has 2 cameras and 3 lenses built in. It’s always an issue, weight vs convenience, but of late I’ve started to lean towards the weight side of the equation. In all sorts of ways. Me and cameras is a bit like you and boats.

I must look up Nikolai on Instagram.
Kelvin Wright said…
The sensor of a digital camera is the bit which measures the light coming through the lens. Sensors are measured in megapixels which is the number, in millions, of individual little sections of the sensor, each one measuring 1 picture element (pixel) ie one dot on a computer screen. Or more accurately, 1/4 of one dot. Sensors can be of varying physical sizes, although they might have the same number of megapixels. On a camera with a physically big sensor, each pixel will be correspondingly bigger and will then be able to measure light more accurately. So, while the number of megapixels is a bit pointless after a while - if you’re looking at photos on a phone or an iPad, anything above about 4 mp is not going to make any difference, and too many megapixels on a physically small sensor wil actually make your pictures worse - the physical size of the sensor is a huge factor in picture quality. The biggest sensors are the same size as old 35mm film frames - 24x36 mm, so are called full frame sensors. Most digital SLRs have sensors that are 16x24 mm, and most point n shoots, much smaller than that. The camera I lust after is a Nikon D850, but they run to over 5 grand, but a Nikon D750 would do nicely and they can be had for less than half that.
Alden Smith said…
Thanks for the explanation, and yes David Hemmings 'Blow Up' seen at the Roxy picture theatre New Brighton about 100 years ago. Today it would be more sensible for me to take the Hasselblad rather than the girl.

One of the cameras that interests me is the Nikon P1000 with its large telephoto lens which would I think be able to photograph a mouse on Mars if so required. It would suit one aspect of my photography which is photographing yachts from a long distance. The problem is its largish size. Of course like owning boats one needs to be sensible and own a bevy, a brace of cameras - a camera for every season, an entirely justifiable situation so long as you avoid justifying yourself.

You will find Nikolai on: https://www.instagram.com/nikolaiasmith/
Kelvin Wright said…
I would imagine waterproofing would be an issue too? Those mega zoom cameras are pretty good. I took a Canon version to Spain one time and had good results with it. Why not get a drone that could fly up to the yachts?
Kelvin Wright said…
Nikolai is good. He has a great eye for the telling detail and a good sense of composition. A lot of his shots have been cropped to fit the instagram format but even so, are well balanced and pleasing. That street photography thing isn’t easy to pull off, but he’s doing it.
Alden Smith said…
There is a reason I like sailing, I never go faster than about 6 knots, suits my level of brain function and aging reaction time - a drone might be a bridge too far.

Waterproofing is a big issue for on board marine photography. Despite its limitations (no wide angle lens) with my little Panasonic I just run it under the tap to get the salt water off it after use.

If I get motivated at some stage to up my game with land based photography I would hope that Digital SLR may has evolved to the point where the cameras are a bit lighter.
Alden Smith said…
I am sure Nikolai would appreciate that comment, I shall pass it on to him.
Kelvin Wright said…
They already have. Mirrorless cameras are smaller and lighter and perform as well as DSLRs. And there are full frame mirrrorless. You can get the New Nikon one for only 7 1/2 grand, but you’d probably want some lenses to go with it and theyre really expensive. It might be shower proof, but you wouldn’t want to wash the salt off it under the tap.
Alden Smith said…
I have been doing some research regarding a new camera. In terms of full frame cameras there are Full Frame DSLR cameras and Full Frame Mirrorless. I think I understand the difference in mechanisims. There may be some advantage in the mirrorless full frame in terms of size and weight. Are there any other advantages / disadvantages that you know of between the types? Some pundits say regarding full frame cameras, mirrorless full frame cameras are the future? In terms of lens which ones do you possess? what makes a basic set?
Kelvin Wright said…
When choosing cameras the place to start isn't the camera, but the question "what do you want to do with it?" That is, what sort of pictures do you want to take? This decides what sort of lenses: general purpose, or specialty ones for close ups or extreme telephoto for birds etc. If you're taking lots of fast moving action, eg sports, you'll want a fast motor drive and high shutter speeds. A big consideration for you would be, I imagine, robustness and waterproofing. Then. just as important, who is going to see the pictures and what will they be viewing them on? If its for phones or ipads then you wont need a lot of megapixels, and probably a full frame camera would be a waste of money. Similarly, how much post processing are you intending to do? Again, if the answer is "as little as possible" or "WTF is post processing?" then you'd definitely be throwing money away getting a full frame camera.

Kelvin Wright said…
But your advisor is right, mirrorless is no doubt the future. Mind you we're not living in the future we're living in the present and currently the best digital camera you can get is the Nikon D850 which is a DSLR. (you can get more expensive DSLRs, but these are designed for war correspondents, fashion photographers, sports journalists and that kind of thing.)There are superb mirrorless cameras from Sony, Panasonic, Pentax and Fuji. The big guns, Canon and Nikon have only recently brought out their full frame mirrorless but they have had some smaller format ones for a few years. The Canon and Nikon full frame mirrorless models are currently extremely expensive and are first generation, so they are no doubt full of faults and bugs and quirks which will be discovered over the next year or two, and the subsequent models will be the ones to have. We are on the very crest of a revolutionary wave in camera design, and like all things electronic, whatever you buy will be obsolete in 2 years time. The DSLR cameras in contrast have reached a kind of apex of design and refinement: their controls and menu systems and ergonomics are as near perfect as dammit. Their image quality is always improving but most of the good ones can have their firmware upgraded so they will remain competitive for a decade or so more. The better ones are extremely robust. But DSLR cameras are big and bulky and heavy, especially with an added on battery case and a big lens.

As far as lenses go, people usually try and have a range of zoom lenses which cover a wide range of focal lengths. My own lenses give me a continuous range of 12 mm to 600 mm in just 3 lenses. The main brands have stock (or "kit") lenses in the most useful ranges which are generally pretty good. You pay extra (a LOT extra) for wider apertures, for apertures which don't vary through the zoom range of the camera (and if you have to ask "what's the point of that?" then you don't need it) and for the sort of clarity which you are never going to notice if you are looking at your photos on an iPad. Alternatively, some people go back to the future and use prime lenses (ie non zooms) Primes from the big manufacturers are often re workings of designs which have been around for years, With no R&D costs they are very cheap. With decades of use they are well honed and give superb results. A full frame camera with, say, 20mm, 35mm, 50mm, 100mm and 200mm lenses is affordable and would give professional results. But if you are going to be taking it to sea, a waterproof camera with a general purpose zoom which you don't under any circumstances change while actually in the boat is probably the only realistic way to go

Of course in all of this there is the question of how much you are willing to spend. A full frame DSLR and a couple of zooms that will do it justice will take care of the best part of ten grand, or maybe only 8 if you shop around. A full frame mirrorless probably runs out to about the same, but there are always sales on last year's model, and hardly used second hand ones around.

Apart from full frame, a good option is micro 4/5, and olympus makes some good cameras in this format. Another thing you might like to look are the retro cameras: Nikon makes a (quite expensive) full frame digital, the FD, which looks and feels and operates for all the world like an F series camera from the 80s. Olympus make the OM-D range which look like old OM-1s. They're made of metal and have much the same appeal as wooden boats and BSA motorcycles.
Alden Smith said…
Yes, the camera should be fit for intended purpose. When sailing I am happy with my point and shoot Lumix. It has a small 6X zoom lens (which must work internally as there are no sticky outy thingies. It can take HD video and has a 28mm Wide lens (which when calculated in relation to full frame size references probably isn't 28mm at all). But being water proof to 10m its almost a dive camera which makes it useful for the marine environment. It wasn't cheap to buy but I can hold it in the palm of my hand and run it under the tap to clean the salt off when I come back from sailing. The problem is that the so called wide lens isn't really wide enough for good on board shooting. But I can solve this by purchasing a cheapish run of the mill compact inter-changable lens camera and choose a wide angle lens to suit - and be careful when the spray starts to fly. Of course a camera like this would only be suitable for my big boat, only a dive camera is suitable for small boat centreboard sailing.

But my main interest in cameras lies elsewhere really. I used to use my Canon FTQL SLR extensively and always got good results. I would like to get back some of the control that I used to have when taking photographs - many of which end up on my Blog.

Also as a way of planning more tranquil interests for the next decade or so I wouldn't mind developing my skills in photography. There is a very active local photography club which organises trips and runs competitions. If I gave up the small boats in conjunction with a knee replacement I would be fit for purposes to take part in all of their walks and tours etc.

Thanks for your comments, your advice on lens pretty much confirms what I have been reading. There seems to be a lot of books to read, information to sift and peoples advice to weigh.

Whatever I end up with in terms of a 'Land based' camera I think I would like a reasonably compact camera - which the continued development of DSLR Mirrorless cameras (including the full frame versions) seems to promise. In the meantime I will continue borrowing books on photography from the local library and getting myself up to speed.

Of course the great leveler in all of this is money. If I could build a camera out of wood I would probably do so - but even I know my engineering limits and my bank account has its own limits.

Camino, by David Whyte

This poem captures it perfectly Camino. The way forward, the way between things, the way already walked before you, the path disappearing and re-appearing even as the ground gave way beneath you, the grief apparent only in the moment of forgetting, then the river, the mountain, the lifting song of the Sky Lark inviting you over the rain filled pass when your legs had given up, and after, it would be dusk and the half-lit villages in evening light; other people's homes glimpsed through lighted windows and inside, other people's lives; your own home you had left crowding your memory as you looked to see a child playing or a mother moving from one side of a room to another, your eyes wet with the keen cold wind of Navarre. But your loss brought you here to walk under one name and one name only, and to find the guise under which all loss can live; remember you were given that name every day along the way, remember you were greeted as such, and you neede

Kindle

 Living as I do in a place where most books have to come a long way in an aeroplane, reading is an expensive addiction, and of course there is always the problem of shelf space. I have about 50 metres of shelving in my new study, but it is already full and there is not a lot of wall space left; and although it is great insulation, what is eventually going to happen to all that paper? I doubt my kids will want to fill their homes with old theological works, so most of my library is eventually going to end up as egg cartons. Ebooks are one solution to book cost and storage issues so I have been  using them for a while now, but their big problem has been finding suitable hardware to read them on.  I first read them on the tiny screens of Ipaqs and they were quite satisfactory but the wretchedness of Microsoft Reader and its somewhat arbitrary copyright protection system killed the experience entirely. On Palm devices they were OK except the plethora of competing and incompatible formats

    The Christmas before last our kids gave us Ancestry.com kits. You know the deal: you spit into a test tube, send it over to Ireland, and in a month or so you get a wadge of paper in the mail telling you who you are. I've never, previously, been interested in all that stuff. I knew my forbears came to Aotearoa in the 1850's from Britain but I didn't know from where, exactly. Clemency's results, as it turns out, were pretty interesting. She was born in England, but has ancestors from various European places, and some who are Ngāti Raukawa, so she can whakapapa back to a little marae called Kikopiri, near Ōtaki. And me? It turns out I'm more British than most British people. Apart from a smattering of Norse  - probably the result of some Viking raid in the dim distant past - all my tūpuna seem to have come from a little group of villages in Nottinghamshire.  Now I've been to the UK a few times, and I quite like it, but it's not home: my heart and soul belon

En Hakkore

In the hills up behind Ranfurly there used to be a town, Hamilton, which at one stage was home to 5,000 people. All that remains of it now is a graveyard, fenced off and baking in the lonely brown hills. Near it, in the 1930s a large Sanitorium was built for the treatment of tuberculosis and other respiratory ailments. It was a substantial complex of buildings with wards, a nurses hostel, impressive houses for the manager and superintendent and all the utility buildings needed for such a large operation. The treatment offered consisted of isolation, views and weather. Patients were exposed to the air, the tons of it which whistled past, often at great speed, the warmth of the sun and the cold. They were housed in small cubicles opening onto huge glassed verandas where they cooked in the summer and froze in the winter and often, what with the wholesome food and the exercise, got better. When advances in antibiotics rendered the Sanitorium obsolete it was turned into a Borstal and the

Return to Middle Earth

 We had a flood, a couple of weeks back, and had to move all the stuff out of the spare bedroom, including  the contents of two floor to ceiling book cases. Shoving the long unopened copies of Sartor Resartus and An Introduction to Byron into cartons, I came upon my  copy of The Lord of the Rings . Written in the flyleaf are the dates of its many readings, the last one being when I read it aloud to Catherine, when she was about 10 or 11, well over 20 years ago. The journey across Middle Earth took Catherine and me the best part of a year, except for the evening when we followed Frodo and Sam across the last stretches of Mordor and up Mount Doom, when we simply couldn't stop, and sat up reading until 11.00 pm, on a school night.  My old copy is a paperback, the same edition that every card carrying baby boomer has somewhere on their shelves. The glue has dried and hardened. The cover and many of the pages have come loose. I was overcome with the urge to read it again, but this old
