Poll !! Poll !! - Colour Problems

Ok - I've lost count and track of the number of posts, threads and forums relating to Colour Problems in LR whether real, imagined or supposed. Giving Adobe the benefit of the doubt in that they would really like to solve this problem (if in fact a problem exists) I thought it might not be such a bad idea to start 1 thread and therefore narrow the scope for searching somewhat. It might also give Adobe a fairer chance at seeing where the problem lies and with what cameras etc. I think it's also reasonable and fair to say that there must be some pretty experienced photographers on this forum and we/they can't be all imagining things. I did read on one thread on this forum that RSP gave more realistic colours straight out of the bag so to speak, and I agree with a subsequent poster who pointed out that this wasn't the case until the Colour Engine was released after which everything was fine. Another post implied that perhaps when the calibration was done for various cameras within LR/ACR or what-have-you that perhaps your particular camera wasn't included, or it varied somewhat from the model/type tested. Anyway, as readers will no doubt agree it all gets rather confusing and all we as users want are 'Proper' colours independent of whether our camera was manufactured on a Monday or Tuesday etc. To make subsequent posts easier to read I would propose that contributors be as succinct as possible and hopefully we'll all have some idea of the numbers involved here and the types of cameras/issues in question. For myself:



Canon 30D - Perceived problem: Over-saturated colours, especially in the Reds which tend towards a horrible Orange (even in Neutral setting). Manifests itself in both RAW and jpeg formats. Camera settings(Picture Styles): All Canon defaults.

Are you saying that you see a difference in jpegs in Lightroom that you don't see in other applications? If so, something else is wrong because Lightroom doesn't do anything to jpegs on import. It seems to me that people are describing only a RAW problem, which is not specifically a Lightroom problem but rather an ACR problem.

I don't think that's quite true. ''Lightroom Default'' is the default preset, not ''Zero'd''. The default tone curve isn't quite linear.

Hmm, I just checked some of my recently imported jpegs, and they are all ''Zero'd'' with a linear tone curve. If I click on ''Lightroom Default'', then it does apply the mild contrast boost.

I may be wrong about what preset gets applied as a default to the JPEGs. I did mess with it last night and I could swear that they were all at ''lightroom default''.

%26lt;br /%26gt;As a poll, this is not a good start! ;)
%26lt;br /%26gt;
%26lt;br /%26gt;But how about posting a RAW file that demo's this over saturation that you see?

Don't know if it qualifies as a color problem, but I posted a yesterday about having problems with posterized shadows in Lightroom ''Develop'' module. With posterization I mean that shadow gradients are not smooth, but rather made up of a few sepparate, clearly distinguisable colors. I don't see this with other viewers on my system (a 32bit color depth Windows machine with a decent ColorVision calibrated LCD screen). I have a couple of screen dumps and original images if anyone is interested:

Picture 3 is how the image is rendered in Lightroom and picture four is the original jpeg in question. Pic 1 and 2 are cropped screendumps of 1:1 images for comparison between Lightroom and Fireworks rendring. Clearly they render the jpegs differently!

Go to the feature requests forum and read the thread called, ''User-selectable color engine''.

I believe ACR 4 has a problem in converting RAW files to Photoshop using either Lightroom or CS3 beta - the colors look fine in sRGB space in Photoshop but saving for the web or proofing colors using Monitor RGB gives a distinct red cast to the photograph. I dont see the same problem using Photoshops CS2 version of ACR (3.7).



This is not imaginary, it is very real.

Are you certain the images are being converted to sRGB?



And why, may I ask, would you proof using Monitor RGB since you are the only person who has *your* monitor?

Yes, I'm using sRGB.



I was told proofing to Monitor RGB would show the same result as using Imageready and that is my finding.
