Creating a Consistent Color Space Workflow Across Adobe Applications

 

Creating a Consistent Color Space Workflow Across Adobe Applications | A Leica and a Dab of DEET...

 

I posted in this portion of the Forum because we should all at least have access to Lightroom. Many people have one version of CS or another and may not realize that when they upgrade the Photoshop Application, at least on my computers, the Color Settings do not carry over. So from ProPhoto or Adobe RGB, one may be working in sRGB, because it is the Adobe Default (in Photoshop) as I explain, without even realizing.

 

I begin with a rudimentary definition of the three major RGB Color Spaces, why I have chosen ProPhoto (suggesting any serious Photographers choose either ProPhoto or Adobe RGB) and then how and where to change Color Settings so that they are consistent.

Also, a tip for Black and White Printing

 

For those that want to get immediately to the meat:

Lightroom 5:14

ACR 6:11

Photoshop CS, CC 7:17

 

For anyone that wants a larger view of the video, here is the direct link to the Vimeo site and specific video.

Because those are settings for the JPG output of the camera. The DNG has no colour space, it is set in the raw developer as William demonstrates in his video. And should be maintained during the postprocessing as long as possible. Once reduced to a smaller colourspace a file can never regain its original gamut.

And always 16 bits, despite the camera outputting a theoretical 8. (it doesn't, but that s another complicated story) to avoid effects like posterization.

Why should I use the color space of ProPhoto, when the M8 takes photos only in Adobe RGB, sRGB or ECI RGB?

 

Agree 100% with jaap.

 

Many other camera manufacturers gray out or make those choices unselectable if shooting raw or DNG. A better choice I think and clearer. Believe me you are not the first to ask that exact question.

However, once the choice in camera is to shoot raw +Jpeg, the values become selectable again and are applied only to the jpegs. Hope that makes sense.

 

If it doesn't please ask again, so one of us can clarify or feel free to shoot me the question via PM (Private Message).

Can you add some insight into how ProPhoto space effects B&W, i.e. the MM raw image?

Are there more grays represented?

I still don't have an understanding of the MM image. For example in CaptureOne, the JFI Film profiles don't have any effect, surely because there is no RGB info. However in Silver Efex 2 the film choice settings work great. Hopefully this is not off topic. I'd just like to understand this.

Thanks

I can't speak for Capture One but I think the most important thing to get a clean image is using 16 bit over 8 and working in either the ProPhoto or Adobe RGB Space.

 

Remember, the MM is a new animal and none of the Gurus have one. There is nothing like it in the 24MP and less Market.

 

As a non-scientific test I opened the same Monochrome image (DNG) in PS CC twice. One with Adobe RGB and the other ProPhoto. I created several curves Layers on one image, Shift Clicked to select all those layers, right clicked to get "Duplicate Layers" and then selected the other image as the Source.

Therefore both images had the exact same Adjustments applied. Had one image been 8 bit there would have been plenty of combing in the Histogram.

 

I clicked the triangle in the Histogram of both so that the new Histogram Information rendered, and both Histograms were exactly the same, exactly.

 

The image itself looked identical through my low resolution Monitor.

The question might be with proper and identical handling would both images print the same? My visceral opinion is yes or close enough.

 

Being as I use ProPhoto for my Color Images, have tons of RAM installed, and plenty of disk space, I'll just keep it there.

 

Edit: Also Calibrating your Monitor with Software and a Puck would be enormously helpful.

Hi there,

 

How do you pay for view? I am a MM/Lightroom only user but find this whole colour space thing most confusing and would love to know that I am maintaining my files at 16bit

You shouldn't need to pay for basic knowledge, that's outrageous. Process your MM files via ACR in either Adobe RGB or ProPhoto at 16 bit, but NOT 'Greyscale' which is the default option.

After you open your pictures using Adobe RGB or ProPhoto work on them and save them in TIFF format. Then you can make copies in JPEG when you need them. As you are coming from the darkroom you will particularly appreciate working on your pictures as a 16 bit colour file ( beyond better quality) because you can add the subtle warm or cool tones associated with different photographic papers.

You're not paying for the knowledge but for the publication of the knowledge.

 

Think of buying a copy of the Bible, Shakespeare, or for that matter any book on basic photography - the 'information' is free, but the production certainly isn't.

 

Sorry for going slightly off-topic, but I think the circumstances justify doing so.

Well I 'published the knowledge' and didn't expect to get paid for it, and plenty of people on LUF would do the same in answering a post for a fellow member's question. But it is particularly invidious that a charge was put on the 'knowledge' after the thread was made into a sticky, and that was particularly cynical.

 

And I think it is out of order having a Sticky where people have to pay for the contents. Sticky's should be basic fundamental knowledge open to all.
