Digital-Image Color Spaces, Table of Contents

My Tech-Related Photography Posts

I initially intended to show a few examples of what happens when an image is viewed in the wrong color space, but when writing it up as a simple blog post, I kept including more background and tangential information, and we now have a seven-page article:

Digital-Image Color Spaces
Page 1: Introduction
Page 2: Test Images
Page 3: History of Color Mis-Management
Page 4: Color Management
Page 5: Chromaticity Diagrams
Page 6: Design Tradeoffs
Page 7: Recommendations and Links

Enjoy!

Thank you for a most informative and useful article — my friends and I appreciate it.

Interesting and informative, but reading a 7-page article on screen is not what I want to do!

Would it be possible to present it as a PDF (and what colour-management problems does that route bring in)?

Great read!

As Michael says, please publish in PDF. Would just love to have it on paper to ease the process of getting my workflow smooth. Right know my colormanagement sucks!

Anyone knows why this is happening:

I load raw photo into lightroom, correct color, WB, exp, contrast and all that in LR.
Open the photo from LR as a psd in PS, colorspace ProPhoto in PS (I have also tried other workspace color profiles…)
The photo shows up in both LR and PS as FLAT! COLORLESS! BRIGHTER!

Also it seems when I export for the web from LR, in 72 dpi, colorspace sRGB, the colors, contrast and vivity of the photo are decreased… I don’t know what I am doinf wrong. Will read your article again, to see if I missed anything…

Thanks!

Hi, Thank you so much for the exif app. I am looking to see date photo was taken, does not say however it says under the ICC profile date time is that the same?

No, the ICC profile date is the date the profile was created; it has nothing whatsoever to do with the date the photo was taken. —Jeffrey
