Matching Difficult Color

One of the most difficult colors to reproduce is a bright Azure blue (a bright mix of blue and cyan). I have tried many methods and color corrections and still have been unsuccessful in close color reproduction.   As you can see in the side by side comparison screen shot, the colors look great on the screen.  But when I print them, the inks and media drop the intensity of the blues and cyans becoming faded, muddied and flat.

 To visualize the effect of print I use a method called “soft proofing”.  I apply a soft (or visual proof) by going to the “view” menu in Photoshop and choosing “proof set-up”.  From that drop down menu I choose “custom” and then select the paper and printer profiles I have for my printer. (In this case it is Epson 9800 Dual Black inks Breathing  Color Chrome White Canvas)  The bottom screen shot shows the results on both of my test prints.  Before I even print them, I know the image on the Left will not even come close to the original despite it being closer in color on the computer screen.

 Because I have had this issue before with this color, I have managed to find a way to reproduce it coming fairly close. I usually work in RGB color mode and send all files to my printer in RGB. (Image>Mode>RGB color).  As this is the color mode of the computer and the color mode that the printer reads I always work in this mode.  However, achieving this brilliant azure blue in RGB is not possible. So I convert the color mode to Lab color and  I am able to create the correct color on screen and from the printer. Color correction can usually be done by the numbers but when it comes to colors that are out of gamut it sometimes takes intuitive reasoning and experimentation.  Don’t be afraid to experiment in Photoshop.  It is sometimes the only way to get the effect you want

HDR with Photoshop CS5

High Dynamic Range or HDR

HDR, or High Dynamic Range is fast becoming a popular photo presentation. Although not new to Photoshop, in CS5 the HDR feature is new and improved.  For a excellent overview of the new HDR feature in CS5 go to  Adobe TV

HDR photos are created by taking muliple exposures.  For the best results shoot using a tripod.  At least three exposures from over to under exposed. The more the better. Some photographers use 6 or even more exposures.

You may notice that I removed an extra bud from the photo. This was done using Content Aware Fill, another amazing feature of Photoshop CS5

Painting in Photoshop CS5

Photoshop CS5: New Feature, Paintmixer Brush

This is just plain fun! I have not painted in years. Since starting in the digital arts and begining this business, I have not had time to paint and had forgotten how much fun it was to push paint around on a canvas. Painting in PSCS5 almost feels like the real thing. A major difference is that the clean-up and paint fumes are non existant. 

It is a power hog, though. Plan to mulititask if you are trying to create a very large image. And save often!!  You will be waiting for the brush to move slowly across the screen smearing pixels along the way. I guess the next move is a computer upgrade to take full advantage of this software.
