ICC Profile Part 2
Posted by bumscientist in Photography on December 26, 2009
After reading up on the ICC profile specification, it seems that there are many ways to define the color mapping, so I think it would be better to start off from reading a color profile. Thankfully drycreekphoto has the color profile for my local printer, which was just updated in August. If I need to look up any color transforms from one color space to another, there is this handy site by Bruce Lindbloom.
Here’s the comparison between the supposed values and the uncalibrated scanned image.

Time to outline the requirements of my ICC Profile Creation Tool.
I’m most likely going to write this in Java for portability. It doesn’t have to be fast.
Milestones and Tasks
- Read ICC Profile for Costco printer
- Write back ICC Profile for Costco printer
- Find ICC Profile for scanner
- Calculate ICC Profile for scanner from calibrated values and scanned values
- Write ICC Profile for scanner
- Test ICC Profile
ICC Profile

I’m too cheap to pay lots of money for color management solutions from X-rite. I already have a gretag-macbeth colorchecker chart, so that’s a sunk cost. I originally planned to use it to calibrate my scanner and camera. I wrote some MATLAB code to analyze the scanned image and did some tweaking on the settings to improve the color, but it was time consuming, because I had to do it iteratively. I looked at the documentation for the ICC profile and I think I can write some MATLAB code to adjust the colors. I think this project usurps the astrolabe, because I haven’t bought the astrolabe book required to design an astrolabe. I also want to scan some old pictures during the christmas break. I’ll put up the MATLAB code for it and try to make some money by putting an affiliate link to amazon for the color checker target.
Aperture v. Lightroom
Posted by bumscientist in Photography on October 18, 2009
I’ve decided to fully embrace digital photography as my hobby of choice. I see many benefits like forcing me to see the world and forcing myself to get out there. To cement my commitment I am sinking some capital into it. Nice lens are expensive, so if I don’t make use of them I’ll be wasting money. To accompany the hardware, I’ll probably need better software, so I downloaded both Aperture and Lightroom trials. So far, I’ve decided I don’t need them. The Camera RAW importing in photoshop works well enough for me. It’s not like I’m a professional photography who has many projects and need something to manage my workflow. I process each RAW individually, so having the ability to batch process doesn’t help me at all. This also is an indication of my decision to post-process pictures in photoshop more. The conclusion is as of this moment, all I need is photoshop. I’ve been watching PixelPerfect on Revision3 and Adobe.TV to get my education on.
