Color Issues
I do most of my processing in Raw and PSD using CS2.
But when I convert to jpg, the colors become slighty washout and desaturated. What happened? I am using Adobe RGB (1998) as the Color Working Space. Can anyone enligthen me? |

Re: Color Issues
Thanks a Million Squid.
Just solved my problem which has plagued me for weeks. Another question, under the "Convert to Profile" box, there is Conversion Option where you can choose between "Perceptual", "Saturation", "Relative Colorimetric" and "Absolute Colorimetric".......what should I choose? |

Re: Color Issues
See http://steves-digicams.com/techcorner/July_2005.html for long explaination on item you mentioned above. In simple words, for most situation, go for perceptual difference as it is more pleasing to the human eye. |

Re: Color Issues
Hi Squid,
To clarification: if the JPG is meant for printing (rather than web), do we still convert it to sRGB first ? Thanks ! |

Re: Color Issues
1) 1 picture taken straight from camera 2) Same picture but have been converted to sRGB in photoshop and the result is that for 1), the colour is more natural while for 2) the colours is slightly more saturated. Both pictures looks good and it really depends on personal perference for saturation. Hope this helps.  |

Re: Color Issues
Sorry, i sort of have the same problem. My photos have slightly different colour in different programmes. However, all this stuff is real greek to me. Can't figure out what all the thread is talknig about. I've tried to follow the instructions but some options ain't even there. Can someone explain in real dummy's term?
 p.s. I'm using a PC and adobe CS. |

Re: Color Issues
The thing about some programs that can display images is that they do not care what colourspace the file is. What colourspace means is this: Imagine a colourspace as a kind of currency. If I give a person $10, the number value is 10, but obviously it is not the same actual value as S$10 or €10 or £10. So, if a program cannot tell what colourspace an image is in, similarly, the value for one colour in that program will not be the same as the colour in another. Of course this a gross simplification of the issue. The important thing is, to trust Photoshop, (no, they don't pay me $$ to say that... :-) ) cause it can tell what colourspace the image is in. Usually it is the choice to print in the sRGB colourspace cause most printers accept colour files from this colourspace. Of course, if you are into really good colour accuracy, you would also need to calibrate, ie. match the colour of the screen with that of the printer...but that is a different story. |
