Several years ago I was having a bit of a moan to a camera salesman about the limited tonal range that digital cameras could capture. I complained about how the clouds were always blown out and shooting into the sun was pointless because most of the sky would go white. I also mentioned that I thought that even the high end digital SLRs still had a long way to go as they weren’t that much better that the little compact point and shoot cameras.
Luckily the guy I was talking to, unlike so many sales clerks, actually knew what he was talking about and he said that I should take a look at the Fuji Pro S3. The Fuji is basically a Nikon body with Fuji’s super CCD in it. The store where the salesman worked didn’t sell the Fuji and at $3500 AUD without a lens it was way out of my price range. Like a lot of things that I can’t have for whatever reason, I sublimated my desire for the Pro S3 and put it on the back burner of my mind.
Some more time passed and about 9 months before I went to Europe last year I bought a second hand Fuji Pro S3 body, over the internet for $650 AUD. I was pretty happy with the results I was getting with my new camera and I took it on my overseas trip where I took over 4000 photos with it.
About a month ago, I helped out a friend of mine (Mark) who owns a Nikon D200, get his beautiful landscape photos from a recent tirp to California, ready for an exhibition. Mark was a bit concerned about some of his shots because the skies were blown out and the clouds had lost their details. I asked Mark if he’d shot in RAW and he said “yes”, so I said to him, “don’t worry, you’ll be amazed at what information we will be able to pull out of a RAW file”.
I was looking forward to showing Mark how much detail we were going to pull out of his skies and clouds. I got quite a shock when I opened up Mark’s images in Photoshop and there was much less detail than what I expected. I’d become so used to the extended tonal range of my Fuji, that I thought it was “normal” and I was really disappointed for Mark. Although we got some nice results for Mark’s exhibition, I knew the Fuji would’ve provided much better results.
A while back I’d been talking to Mark about his decision to buy the camera he did, and he said he’d been influenced by Ken Rockwell’s camera reviews
To me Rockwell is one of those guys who would have people believe he knows all about cameras. From where I stand, I’d say that he still has a lot to learn. Here is an example of what he has said on his website:
“The Fuji Fujifilm S5 has highlight dynamic range clearly better than any Canon or Nikon camera I’ve ever used. This is too bad because it makes very little difference in real photography. I had to go out of my way to contrive these examples. Cameras can’t fix bad light, only photographers can.”
My response in a word:
I think what people like Rockwell are lacking, is an understanding of how important post processing of images is.
Just like in the old days with film, one couldn’t get a really good image until they’d figured out how to develop their own negatives and do their own printing. Darkroom skills used to be essential to get images to look like they did to the photographer when they saw the scene originally.
“What!” I hear you cry.
Yep, cameras don’t tell the “truth” as we know it. Cameras, film, CCDs only approximate what we see. The huge difference between an image taken with a camera and a scene seen with the human eye is that the eye has a brain behind it that makes all sorts of decisions about how the scene is going to be interpreted by the viewer. Cameras, for all their electronic wizardry are basically very, very, very dumb.
Have you ever noticed how flat and boring so many photographs are when you get them back from processing or look at them on you computer monitor in comparison to when you were looking at the original scene? The camera has no way of prioritising what is important to us; what should be emphasised and what should be ignored. To a camera, every scene is made of elements that have no meaning or aesthetic weight.
Your eye has a far wider acceptance of tonal range than any film, camera or CCD. Plus our brain automatically adjusts to what we are interested in, whereas a camera has no way of knowing what is important to us. Now I know there’s bound to be some smart arse reading this, who will pipe up and say, “oh yeh, what about exposure compensation?” The trouble with exposure compensation (particularly with digital cameras) is that if you expose to retain detail in your highlights, your shadow detail will be lost, and vise versa if you expose for the shadows.
Back in the days when film was king, the maxim of, “expose for the shadows and develop for the highlights”, was the catch cry of the masters of the darkroom arts like Ansel Adams and Edward Weston. The old photographic masters knew that most of the tonal information could be captured if you knew how to control the process.
Nowadays in this age of digital cameras, the darkroom has been just about replaced by Photoshop.
Now many people think Photoshop is for “jazzing up” images and that somehow using it is “cheating”. These same old purists would think nothing of selecting a particular film stock for it’s saturated colours, or printing papers for it’s rendition of flesh tones or ”pushing or pulling” colour film to affect its colour balance, etc.
Back when one worked on an image in the darkroom, it was accepted practice to dodge and burn a print, because of the fact that film and the paper being printed on couldn’t deal with the complete tonal range. The same goes for the printing industry. The highest quality fine art books, especially those with high quality black and white images, use a process called “duotone” to get a tonal range that is close to a hand processed photographic print. A duotone is basically two images at either extreme of the tonal range that are printed on top of each other.
So in a long winded way, I’ve tried to point out that it is necessary to have as wide a tonal range as possible so that the end product image, can be as close as possible to the scene first seen by the photographer. The wider the tonal range, the wider the options are when it comes to how one wants an image to look in long run.
The trouble with reviewers like Rockwell is that they seem to have limited knowledge about what’s really going on when one takes a photo and what’s really important. So many of the specifications that people masturbate over, are in the grand scheme of things, not that important. Unless you’re a sports or wildlife photographer, who cares if your camera shoots 5 frames a second, if your tonal range is crap and it causes highlights to be blown out, while your shadows are just black blobs?
When it came to the misrepresentation or misinterpretation of facts, my grandmother used to parody an unscrupulous cloth merchant, saying, “never mind the quality, feel the width”. Just to emphasise how ridiculous, whatever illogical or misleading thing was being said.
Much of what is in reviews isn’t all that relevant to the photographic cognoscenti. Knowledge is power, and it pays to be an educated consumer. The trick, and this goes for just about everything in life, is to pick the right people to listen to and learn from.
For me, the best on-line camera reviews are at
Yes their reviews are very in depth and require a fair bit of technical knowledge to interpret, but I’d say just take a deep breath and look up the terms that you don’t understand as you go. Eventually you will build up enough knowledge to make informed decisions on you own instead of being misled by people with big holes in their knowledge like Rockwell.
One more thing, if you are shooting to save your files as JPEGs, do yourselves a favour and stop it. Start using RAW because you will get far better results because the RAW file format is much more versatile as it contains way more information.
Here’s a video tutorial on how to adjust RAW files as they are opened in Photoshop.
This next tutorial is on another important Photoshop technique, “masking”, by the god of Photoshop, Russell Brown.
