Is there any reason to shoot sRGB????

[Marsu42]

Adobe's linear gamma and proprietary version of ProPhoto, named after the developers wife Melissa Gaul, is still for all intents and purposes ProPhoto. I was trying to provide a simple explanaton for a user who may be intimidated by color management.

Thanks for not burdening us with accurate explanations, but keeping it simple :->

We don't have any of those around here ... just those KODAK self-service kiosks.

Ugh, time to move ... where I live (Germany) most internet printing sites are wider gammut than srgb and also a lot of local print shops.

Ach echt? Das interessiert mich. Nenn mir doch mal einige Internetdruckereien die auf große Farbräume setzen.
Oh really? I'm interested in stuff like that. Name some german printing sites which are using wide gamut colorspaces.

Oy. The first page is painful to read. One poster should be banned from ever discussing color management. ;D

As stated above, in-camera doesn't matter unless your working output is JPG (or TIFF). RAW images contain a wider gamut than either AdobeRGB or sRGB and will not be changed regardless of camera setting. It is recommended that any non-RAW images be created in AdobeRGB and only changed based upon the output device. You can convert AdobeRGB to sRGB (for web or monitor output) or any other ICC profile (for printing), but you can't convert backwards (sRGB is the smaller color space). Despite claims to the contrary, as long as you are using ICC-aware software (photoshop, lightroom, etc.) color management and conversion are relatively straightforward. If posting to the web output to sGRB, for a professional printer install their ICC profile (which will almost always be based on AdobeRGB) and output to its format.

Great info on Lightroom above. For more check out this link:

I'm using this one: http://www.saal-digital.de/service/support/artikel/Article/show/sartikel/icc-profil-im-photoshop-einrichten/ ... by delivering pictures in srgb you might loose some gammut their devices provide. Ymmv a lot if you actually see the difference between a shot delivered in srgb vs argb though, but you can check by using softproofing with the respective icc profile.

Sure. If you are producing images that will be used for the web and are shooting in JPG.

Lets say, for instance, you are shooting photos for a marathon. You are shooting say 2000 runners, and this is basically a churn and burn, you turn in your card, get paid and pretty much all they process is maybe slight exposure adjustments, but pretty much those images are what they are. If they are AdobeRGB, then ALL of those images will have to be converted to srgb to look o.k. on the web.

This is true, however the reverse is also true - and irreversible. If they are all sRGB then your client will be limited in creating print copies. Down-conversion is painless, up-conversion is impossible. It's a good idea to check first if you're often in this situation.

Another good reference for further education. http://www.steves-digicams.com/knowledge-center/in-camera-color-spaces.html

cyberlab.at uses a wide gamut chain and also supplies the proper color profiles for softproofing. In case the printers are to far away or it's about media types I don't want to handle myself.

Just to add my two cents;

Lightroom uses ProPhoto RGB as it's internal color space so I use that within my own workflow to keep things simple. So, if you edit RAW's in lightroom, you use ProPhoto.

No it doesn't.

All images displayed in the Library Module are jpegs in Adobe RGB, these are internally created. I am not 100% certain if it displays tagged jpegs in their native space, like in the Slideshow Module, or if they are all recreated as Adobe RGB previews.

In the Develop Module it has it's own colour space, although the chromacity levels are based on ProPhoto it has a gamma of 1.0, ProPhoto has a gamma of 1.8. You can't ever see the internal Lightroom Develop Module colour space, it is called Melissa. The images you see in the Develop Module are Melissa colour space with an sRGB gamma tone curve applied. This is why you sometimes see a colour shift when switching from the Library to Develop Modules.

In the Slideshow Module RAW files are displayed in Adobe RGB and tagged jpegs in their native colour space.

In the Web Module all images are displayed in sRGB.

Lightroom is a colour space marvel, it is extremely complicated under the hood but they did a very good job of the methodology, basically it reminds me of a swan on a lake, it looks serene and unmoving on the surface, but below the water it is paddling like a paddle steamer.

Having said all that, only for the sake of accuracy, as has been pointed out, if you are shooting RAW and using Lightroom it is close to irrelevant with a nod to the improved histogram in Adobe RGB, if you are shooting in jpegs and doing little or no post processing then sRGB makes more sense especially if you upoad or email many of your images. If you shoot jpeg and do extensive post (but why would you!) then Adobe RGB will give you more tonality to maneuver before posterization kills your image.

Adobe's linear gamma and proprietary version of ProPhoto, named after the developers wife Melissa Gaul, is still for all intents and purposes ProPhoto. I was trying to provide a simple explanaton for a user who may be intimidated by color management. But, if you need to feel smarter than everybody else on the internet, than by all means say "No it doesn't".

Well you failed.

The request for help was specifically about Adobe RGB and sRGB as selected in camera. Adding a third, and unselectable, colour space into the mix, and mislabeling it to boot did nothing to help anybody let alone provide a 'simple explanation', so forgive me for trying to correct some of your inaccuracies.

If you are using Lightroom you don't have a choice regarding colourspace and it never uses ProPhoto, all internal colourspace handling is automatic until export. If you are shooting RAW and using Lightroom it doesn't matter which colourspace you assign in camera as it will ignore them both anyway.

The Melissa colourspace is not proprietary, it is freely published and usable, just take the chromacity values of ProPhoto and a gamma of 1.0. To label Melissa Gaul as 'the developers wife' is also a gross misrepresentation, true she is married to Troy Gaul one of the original developers, but she was also the Adobe QE manager for Lightroom and as such played a key roll in the development herself. Indeed she is still at Adobe but moved from her managers position in 2007 after over 9 years.

Now, having said all that I still don't feel smart, but I also didn't feel the need to bring in spurious misinformation into this thread and then try to put somebody down that pointed out some factual errors.
