Just reading a magazine this morning for canon cameras which I've found a refreshing read as it's purely based on Canon... and it has the following coment in an article about 50 tips on your camera you might not already know!

Burried in your menu is colour space... change this to Adobe RGB to record a wider range of colours and better printing results...

Sounds fab... so why dont they have it set to that as a defalt instead of sRGB?

What are the con's to moving over to Adobe Colour Space?

Any other advantages?

I shoot in RAW so does this even matter to me?
 
From the Ken Rockwell website...

Color Space

Don't touch this unless you really know what you're doing and print your own work.

sRGB is default. It's the world standard for digital images, printing and the Internet. Use it and you'll get great, accurate colors everywhere all the time. Like what you see in my Gallery? That's all coming to you in sRGB. Use it and you'll automatically get great, saturated and accurate color everywhere. See Color Management is for Wimps for examples.

sRGB is specified in IEC 61966-2.1, which you may also see when examining color profiles. That gobbledygook means the same thing as sRGB.

Adobe RGB should never be used unless you really know what you're doing and do all your printing yourself. If you use Adobe RGB you will have to remember to convert back to sRGB for sending your prints out or sharing them on the Internet. Otherwise they look duller than sRGB!

Adobe RGB squeezes colors into a smaller range (makes them duller) before recording them to your file. Special smart software is then needed to expand the colors back to where they should be when opening the file.

If you have the right software to re-expand the colors you theoretically might have a slightly broader range of colors. However, if at any point in the chain you don't have the right software and haven't attached the AdobeRGB profile you'll get the duller colors as recorded!

Web browsers don't have, and print labs rarely have, the right software to read AdobeRGB. This is why people who shoot it are so often disappointed. Even if a place has the right software, if you forget to add the AdobeRGB profiles to your files these places still won't read them correctly and you'll get dull colors.

Adobe RGB may be able to represent a slightly larger range of colors, but no screen or print material I've used can show this broader range, so why cause yourself all the trouble? I've experimented with 100% saturated grads in these two color spaces and never seen any broader range from Adobe RGB either on my screen or on SuperGloss Light jet prints.

Worse, if you're the sort of vacuum-operating geek who wants to shoot AdobeRGB because you read about it in a magazine article, did you realize that because the colors are compressed into a smaller range that there is more chroma quantization noise when the file is opened again? Ha!
 
I'm reading the same mag :thumbs:

I was under the impression that home printers were better at printing sRGB and it was advantagous to keep everything the same colour space.

I'm pretty sure in one of there previous editions - I will look through and check - that they recommended using sRGB :thinking:
 
Thanks... thats a kinda conclusive NO then...

So who is Ken Rockwell and why should I listen to him?

Not being cheeky... just interested to know as never heard of him before? And cant believe a mag would be soo wrong!

This was my first read of this mag... but must admit... apart from this glitch it's quite a good read!
 
what is said above is completely true
I tried Adobe sRGB once (must have the best for MY pictures) - total disappointment
changed back to sRGB - massive relief all round

I wouldn't touch Adobe sRGB with your barge-pole!

Yes, I got a subscription for my birthday end of last year and overall have been pleased with it, have found some usefull tips and at present, will happilly renew the subscription when it comes around. :thumbs:

(if you like the mag, have a look for the latest offers on the web, I think they were doing a trial 3 month offer recently, which was very cheap)

Do you mean Adobe RGB that you tried and wouldn't return to :shrug:
 
So what does one set Colour Space to on the camera sRGB or AdobeRGB for this newbies info TY.

I haven't read the mag, but from what you say in the OP, it's not wrong at all. And neither is good old uncle Ken, they don't seem to disagree with each other in the material posted above.

Who is Ken Rockwell? He's a guy who gets paid to polarise opinion, and you probably shouldn't listen to him a lot of the time. :p (Ok, he has a heap of experience as well, and probably knows a lot more than I do).

For what it's worth, I shoot in AdobeRGB, as do 95% of the photographers I know. Funnily enough, a few of us did test printing of business cards and postcards last week in various colour spaces. Adobe RGB was easily the most accurate.

:bonk: yup :bonk:
 
The articles/information you'll find on the www etc are probably split 50/50 as to whether you should use Srgb or Adobe Rgb, the more you read the more difficult it becomes to reach a conclusion !!

I think it's easiest to look at your "end product" and then decide for yourself which one makes sense....I used Argb for a good while, after reading several articles singing it's praises, but after reviewing things recently it didn't quite make sense as the majority of my prints are sent to a print company who accepts files in the SRGB format only..

Having now moved to a complete Srgb workflow I haven't seen any discernable difference in the prints, it's also simplified my workflow slightly, so personally I'll be staying with Srgb from now on.

I'd be amazed if you get a consensus of opinion on here regarding colourspace (or anywhere else for that matter) :bonk:

Im just going to stick to sRBG I think... seems easier... and I'm not really a huge computer photographer anyway... still prefer being out with the camera taking the images as to sitting much on the comp tinkering...

I think im better the devil I know!

It's pretty easy to reach a conclusion once you get past all the technical guff behind it. What it really boils down to is use the smallest space you can that

a) the output device can handle and
b) covers the colours found in the image

Use a larger space and you're wasting bandwidth and risk banding. Use a smaller space and you might lose some of the extremes of saturation. For most people in most situations sRGB is more than enough :thumbs:
 
If you look at the colour space of the typical monitor, and that of most inkjet printers, then you'll find that they around that of sRGB. So if in doubt that's the on to use.

However you are then limiting your images to a smaller colour space should technology come along and give you the ability to produce a wider range of colours. We are now seeing some large format inkjet machines which can exceed the colour space of sRGB, but not too Adobe RGB.

For the majority of people I would suggest that sRGB is probably the best option.
