If you shoot RAW and take the image to Photoshop, do you use Adobe Camera Raw? If so, you use the built in profile, if you like it or not. It is not an optimal profile, mildly put. Adobe Camera Raw uses the exact same engine as Lightroom, only the user interface is different. That said, I don't use Lightroom either and often use a different RAW converter than ACR.

 

 

 

warning: this will look bad via webpage, so download it and open it in either LR or photoshop.

 

 

 

Interesting, When downloading the image (save image as... in browser, there is no download link) and inspecting it, it does not have an embedded profile or tag. Maybe the forum stripped it, who knows. Most browsers will render it assuming sRGB, if it is not, then there is a problem indeed. However, I opened it in Photoshop, tagged it as sRGB and it looks exactly the same  as in the browser. So that is expected behavior. (And yes, I have a calibrated monitor, but that does not matter in the comparing) That leaves me with the following questions: what browser do you use, and how did you tag the image when opening in PS?

You can create any profile you want in Photoshop.

Yes Jaap, I know, thank you. Somehow this discussion became a mixup between the original subject, the camera profile used in ACR and Lightroom (a .DCP file), and the ICC color profile used for encoding the final image, such as for example sRGB. And I have to admit: that was my fault. I believe people like you and me certainly know our way around those things and they are not really hard to understand really, but not everyone. Sometimes it is hard to cater both groups.

But I repeat my statement to all: the built in camera profile in Lightroom and ACR as shipped by Adobe is not optimal, mildly put, especially for skin tones. It is worth while to create your own profile or profiles using a color-checker card and the Adobe Profile Editor (preferred by me) or the software that comes with the color-checker when you buy one. Tip: try to light the card as evenly as you can and prevent colorful surroundings when shooting it.

This benefits almost every camera that you shoot RAW with, besides the Q.

For those who do not want to go through that process, I will send you mine for the Q if you drop me a mail at bartvanhofwegen@gmail.com

Correct. But the newest ACR CC has a large number of  profiles built in and a special panel to choose them. None are 100% optimal, but they cover most situations. I don't know about LR - never use it if I can avoid it.

 

One tip: when shooting under horrible mixed light, say, LED and daylight mixed, use the grey card white balance; it will turn up too cool, but that is easily corrected and it provides the best starting point.

True, things are slowly improving at Adobe. I guess -but like you I do not really know due to avoiding it- that Lightroom should offer the same thing, it is basically the same engine in a different wrapper. Or so I've been told...
