sRGB vs. Adobe RGB Can't Post

Could someone tell me in a nutshell how to handle this?
What should the camera be set at?
Any hints to know to deal with this proper?

Most labs use something close to SRGB. You do get a wider range in Adobe RGB but the max colour on either end of the vector in Adobe RGB is equal to that in SRGB.

So what happens if you shoot in Adobe, then the lab prints in something similar to SRGB you're slicing off some of the colour information on either end of the vector. I'm terrible at desribing things, I hope this made sense.

Short answer SRGB unless your lab uses Adobe - which I think most do not.

I suggest you shoot in aRGB, work in 16-bit aRGB in post then just after your very final step (which is usually sharpening) convert the image's space to sRGB to be printed or displayed on a monitor. Make sure you keep an aRGB version though! Once you convert the numbers to sRGB there's no way to go back.

If it's just weddings, sRGB will let you work quicker and get more consistent colour. For other work, I have just moved from Adobe to ProPhoto, the new default in Lightroom. Prophoto looks like it will be the new standard for high quality printing and will be properly supported soon by printers and monitors. At the moment the advantages are more theoretical but it is good insurance for images that will be kept to be printed out regularly. And you have to think that Adobe wouldn't make the change on a whim. I hope Laugh

I've noticed that sometimes Ken talks in circles on some topics. For example in this article he says how aRGB is bad, but then says 'if you know exactly what you're doing then go ahead and use it'. Why would he recommend it to color management experts if it's a bad thing?

I see aRGB as a space containing many more colors than sRGB. It's why I shoot in aRGB and work in aRGB then use Perceptual or Relative rendering intent (whatever looks better in preview for any given image) to convert an image's numbers to sRGB at the end of the editing process. One day soon affordable inkjet printers and lcd displays will be able to render all the colors in the aRGB space. Heck, I'm not sure but the Epson 1800 might already be able to. People with aRGB files will be ready for it when that happens, in any case.

Do a test, shoot the same pics in both Adobe and srgb, get them printed and see what you like best.

I can only give my experience on what I've learned from teachers, what I've done and am happy with, and also, I saw that Gary Fong says the same thing on his training dvd's too.

Do some tests and see what you like best and what you think is necessary.

He said to use SRGB because that is closest to what labs use. He also said that most people would be hard pressed to see the difference between a shot done in Adobe and srgb. If you shoot in adobe rgb then have it printed in srgb you're slicing off information at either end of the spectrum and your picture is going to look like it is lacking colour information. He showed a demo of the photos done this way. The one shot in adobe then printed in srgb looked like crap compared to the ones shot and printed in srgb.

Supposedly the end of the spectrum in adobe is the same as the end in srgb, there is slightly more in between in adobe this is why their spectrum is slightly larger. But in the end he says there isn't much difference and you're better off to simply shoot srgb. That's what he shoots.

I figure if it looks good, clients are happy and it is adequate for what you want to show, then why waste the extra steps doing conversions. For weddings it isn't necessary as no one is even going to tell any difference.

One other tidbit of info that he mentions a few times is that he only ever shoots in medium jpg for weddings. He also had an 8x10 which was shot on a 3 megapixel camera and one shot on a 12 megapixel camera and it was very hard to see the difference side by side, if you weren't comparing right beside each other it would be very hard to know which is which, the photographers there couldn't tell unless they were side by side.

I use sRGB myself. My lab uses sRGB, the web displays sRGB, so I really see no point in messing around with aRGB at all. Maybe if I was doing specific corporate work, and the colours where super important, I'd look into it more. But for weddings, sRGB is fine. IMHO.
