The point is when choosing a lens, colour rendering and contrast are so easily adjusted now they shouldn't be an important factor in purchasing decisions.
It seems we're still on different pages. I have mentioned "vision", because I see difference in the original file. I have attached an example. Let me attach a sample photo later
It would be great if you could add sample photos too.
Ok, here is what I am talking about. I just did these images quickly for this thread, I used complete auto settings if I wanted more accuracy I could go into the calibration software and customise it to my hearts content.
I took two pictures of the same colour card in the same place, one with an EOS-M and compact fluorescent light bulb, the second with a 1Ds MkIII, 24-70 and a 600EX-RT. Those are the two left hand images, I then calibrated them and white balanced them and those two pictures are the two on the right. I think you will agree the two on the left are vastly dissimilar with very different colour characteristics, but the two on the right are very similar. This is not just a WB adjustment, the colour swatches change in relation to each other too.
I did not touch exposure, obviously the two images have a slightly different exposure as well.
As I said before, it's not about calibration. It's all about how far you can go from your initial state.
Below is a sample comparison (2 old images taken with 2 different high-end equipment sets):
- left-hand side image is worse for me, because I cannot push the colors further than they are (e.g., I can't make the whites whiter on the dress, because specific areas are burnt out due to initial color corrections);
- right-hand side image looks nicer to me as it gives a feeling of richer tonal gradations; those cyan and orange colors add some kind of luminance to the image, and the whites look whiter without being burnt out.
I understand that in this case the difference is minuscule. But if I don't have the first image limiting me, I would be able to go further with the second one. On the left side the main image lacks additional colors from the right image (cyan and orange). Let me demonstrate how pushing specific colors to a ppleasible end point works on both images:
This difference is not something I've noticed once, equipment is one of three variables in the equation we all having troubles with (IQ = photographer + environment + equipment). In the end I get a cheap-looking left image compared to something I want to get on the right-hand side. Needless to say, the workflow for achieving these looks differs – image on the right is something that is much easier to get than the left-hand image that ends up being worse to my eye (because of the interfering colors).
Color calibration was something I did when I opened photography for myself, a few years after I figured out that it's meaningless for me.
