Mr D noticed that quote these are in Adobe RGB colour space. May prove an issue when printing... un quote ...
I wonder if people understand all the different types .. I would like a simple explination
when I open my raw files they are in adobe RGB (1998) is this ok ? when I print I alter the colour space to the profile used by DSCL labs
could someone offer a guide as to what the profiles should be used for
the options I have in camera raw 6 are ....

ADOBE RGB (1998)
COLOR MATCH RGB
PROPLUS RGB
sRGB IEC61966-2.1

Thanks

"Adobe RGB is irrelevant for real photography. sRGB gives better (more consistent) results and the same, or brighter, colors. Using Adobe RGB is one of the leading causes of colors not matching between monitor and print.
sRGB is the world's default color space. Use it and everything looks great everywhere, all the time.
Adobe RGB should never be used unless you really know what you're doing and do all your printing yourself. If you really know what you're doing and working in publishing, go right ahead and use it. If you have to ask, don't even try it."


says this site. (http://www.kenrockwell.com/tech/adobe-rgb.htm) And he's a clever bloke!



I recently upgraded my camera, and sure enough, Photoshop's raw converter suddenly wanted to input pix at 240dpi. I upped it to 300 and so it has stayed, similarly, I have the colour space set to sRGB (one click and it's right forever).





I now hand you over to an expert...

Okay, let's open this discussion up again. I set my camera to sRGB, but when I look at the images I have saved as JPEG after processing in CS3, the file reads Adobe 1998.....Today I took some files to be printed, and ALL of them came out about 40% darker than I had expected. I was trying to print up some 8x10's to send off for a photo contest at Sam's Club (which I imagine is like Costco's) and I was very disappointed. How to I change the profile to save JPEG in RAW processing in Adobe CS3? I should get better results if I save as sRGB, am I right?

This is what I found on my "help" pages in CS3:

Adobe RGB is recommended when you prepare documents for print, because Adobe RGB’s gamut includes some printable colors (cyans and blues in particular) that can't be defined using sRGB. Adobe RGB is also a good choice when working with images from professional-level digital cameras, because most of these cameras use Adobe RGB as their default color space.

I use sRGB for all use, and find it works for me when i print. You can change the profile in Photoshop, i just find it less confusing to use one profile for everything.

Ok - let's list a few things that may help Natatlie...

1. If you're shooting RAW - then the colour space set on yoru camera makes no difference. RAW has no colour space - it's raw data.

2. Colour space is chosen and applied to your file as you export them from RAW to TIF or JPG. Adobe Camera RAW default is AdobeRGB. If you click the link at the bottom of the converter screen you can change it to sRGB. It will remember this new setting for next time.

3. Printing in Adobe RGB is only ok if your printer is set up to print in AdobeRGB. If using an online lab they will almost certainly want sRGB - or they will provide their own colour profile for you to install and apply to your files before you upload them. The lab I use provide a profile but accept sRGB too.

Life is so much simpler if you use sRGB for everything.

Not related to printing, but I recently found out that not all colour profiles are supported by web browsers, but sRGB is! So if you post in anything other than sRGB you risk it not being displayed properly!

This first images is what I took in to print at a big lots club store:
to me it looks very bright and light, the frog is perfect...how does it look to you guys? printable as is? It WAS saved as Adobe RGB 1998

this is a scan of the print I had made, and this is the "lighter version" after I complained and they reprinted it. The first one was even darker, and he said the machine automatically does a photo enhancement on everyones photos UNLESS they are asked to turn it off. Crap...even the "improved one" is too dark.

I am going to save as sRGB from now on, and go to another place, and see what happens. I used to take them to a local drugstore, and they knew me, and they printed excellently, but they were bought out, and their machines were taken out and the new company put their own ones in, so ALL their stores are now "quality controlled" and I'm not sure how they will print there, now.
