Lightroom RGB Percentage vs Photoshop RGB numbers
Trying to get my Lightroom refined images as close as possible to Photoshop optimized versions, I discovered that the Lightroom RGB percentages do not match Photoshop RGB numbers. Lately I have been finishing my underwater images in Photoshop, as Lightroom does not offer the amount of color correction control I waned. However, reimporting my corrected [...]
Photoshop CS4 bug – Color Sampler to Curves shortcut in Windows

I just updated my Firefox browser to version 3.5, went to a favorite page on CNET that has a number of test images, and it appears Mozilla have changed the colour management capabilities on the version 3.5 Firefox browser.

New Safari 4 Browser Release – Color Management Error
Apple has released a new version of the Safari browser. I like to use the Safari browser for its colour management capabilities, but Safari 4 appears to have a error in how it handles ICC profiles. I am traveling at the moment, so do not have the benefit of my large screen, but am running [...]
Be Careful with Scanner Auto Settings
Using scanner auto settings can cause problems when scanning images. Turning off the auto settings, and using manual settings can make image correction easier and more accurate. The Problem I was recently scanning some images using my CanoscanFS4000US slide scanner (Canonscan FS4000US ICC profile). After scanning the images and assigning the custom profile, a number [...]
Canoscan FS4000US ICC Profile
I decided to get serious about profiling my Canoscan FS4000US slider scanner, due to having several years of slides from the period before my switch to digital. My Canoscan FS4000US scanner is a couple of years old now (costing around $1500AUD when new), but provides high resolution images from slides and negatives. For years I [...]
Blue white stripes

The visibility was a little hazy after the series of storms we have been having, but managed to grab a couple of shots new species for my collection:- Volitans lionfish and Minor Notodoris nudibranch. But I was more intrigued [...]
Samsung 2243BWX Monitor – Part 2
I just remembered today that the Samsung 2243BWX monitor I purchased recently came with a pre-made (or ‘canned’) ICC profile. For interest, I decided to compare the canned profile with the Spyder 2 colorimeter ICC profile using the Chromix ColorThink software. The 2D view of the profiles show the canned and measured profiles follow each [...]
Samsung 2243BWX Monitor
I have been working on a windows laptop for a while, and spending a lot of time at present in front of it, decided to look at an additional screen. Ideally I would have liked to purchase an Eizo screen, but they aren’t within my budget just yet, so I looked at various screens available [...]
