Title: ssRGB or aRGB?
Post by: mgts517 on November 11, 2005, 01:37:15 pm
Can someone recommend which setting I should use when converting my raw images?
I'm shooting with a Canon 300D,process in cs2.
When I save the image ,should it be sRGB,or aRGB...which will yield me a better print?
Any help would be appreciated-
Thanks ,
Mike

While based upon a different camera, the concept is the same so read this:

  Andrew,
Thanks for your reply/link.
It was an extremely informative article .
 Let me see if I've gotten this right:

 1. If I convert the file to  aRGB,I may not see any difference in the final print unless, my printer is capable of reproducing that much color?
2. Monitor must be profiled for optimum color output?
3. aRGB will yield more detail and color separation with more greener images{landscapes}?
Am I getting this right?
Thanks again,
Mike

-->If I convert the file to  aRGB,I may not see any difference in the final print unless, my printer is capable of reproducing that much color?

And the scene data exceeds sRGB (VERY likely). IOW, shoot a gray card, doesn’t make much difference.

-->2. Monitor must be profiled for optimum color output?

Always!

-->3. aRGB will yield more detail and color separation with more greener images{landscapes}?

More detail, no. A higher saturation IF the scene and output device can use it, yes.

You should also read Michaels article

I read the article, but I don't see the option for ProPhotoRGB in EOSViewer (though I have found it in Photoshop).

At the risk of asking a stupid question, how do I get the RAW converter to convert it into the ProPhoto color space?

larkvi,
Thanks for your reply,
Wouldn't it be better to stay with the adobe settings,well, if for no other reason thats what Michael is using,atleast he was in VJ #12 & 13.
I can't seem  be able to convert the color settings for my printer to this color space.Shouldn't I use the same settings thoughout the whole process? {raw-conversion-printer}
However
Photoshop CS2 does give that option,for that color space
aRGB & sRGB seem to be more universally accepted,especially for someone like myself,an amatuer photographer.
Even Michael in his article states that this color space could prove to be dangerous,& possibly yield disastous effects.
Please correct me if I'm off on this.
Thanks for the link on Michaels article,it was very interesting...like all of his articles are.
Mike

Use ACR instead of DPP.

They seem to have removed the photoshop 7 version from the website, so I will keep using aRGB until I manage to get a copy of CS/CS2.

(And, were they still charging $99 US for the plugin, that would make it almost half the cost of buying the OEM student version of Creative Suite CS2 Premium, anyways, which would suggest I should just get CS2.)
