Color Mechanic

Better Than a Mechanic

There are quite a few Photoshop plug-ins on the market. These are small helper programs that are designed to work inside of Photoshop and which generally provide access to capabilities that Photoshop doesn't provide directly.

Color Mechanic from Digital Light and Color is a new offering that provides photographers working in colour with a unique capability — being able to change just one specific colour to any other colour, or more usefully, to any shade or variation of that original colour. Big deal? You bet!

Let's see how it works, why you would want to use it, and more particularly how well it does its intended job.

Get To The Point

Once the plug-in is loaded into the correct directory in Photoshop it is accessed from the Filter menu. When activated you see a screen similar to the screen capture below. 

The photograph that I used for this example was taken with a Canon EOS D30 on a gray overcast day in early October. It was the kind of day that I wished that I was shooting Velvia so as to benefit from the enhanced colour saturation that this film provides. But, film doesn't fit well in the D30, even Fuji Velvia, and more to the point, I was shooting from a moving boat and needed to use a minimum of ISO 200, not the ISO 50 of Velvia.

Color Mechanic made enhancing this photograph ridiculously easy and quick. Using the eyedropper tool I first clicked on an area of green foliage in the left-hand window. This placed a control point in the color Hexagon beneath it. I then dragged this point to the right, into the more saturated green area of the color Hexagon. Instantly the preview window on the right showed an increased saturation in the greens.

Similarly, after using the magnifier to better be able to isolate the yellow leaves, I clicked on one. This placed a control point in the yellow area of the color Hexagon. I dragged this a bit into the yellowier area. With that control point still selected I moved the Brightness slider, located between the two window, to slightly increase the brightness of the yellows in addition to their saturation. Finally I clicked on the tree bark and moved that control point over a bit to make the bark colour less blue, and therefore more neutral.

You can see an enlarged version of the final color Hexagon below. You'll see the three control point and how much I moved them to achieve the effect I wanted.

 

 

 

 

 

 

 

After clicking OK the image was changed. Below you can see both before and after versions.

Before Color Mechanic

After Color Mechanic

One of the powerful features of Color Mechanic is that it is very easy to lock any colour, so that when a close-by colour is changed the effect is restricted to just the tonalities and colours that you want. This is simply done by clicking on any colour and not dragging the control point. Simple and intuitive once you understand it, just as with the rest of the well designed interface.

If I had to do all of this using Photoshop's standard tools this might have taken me 15 to 20 minutes and would have required the fussy use of Masks. Using Color Mechanic I was able to accomplish the same thing in about 30 seconds. But, like any powerful tool, what Color Mechanic can do can be easily overdone. Subtlety in how you use it is important. 

The Plug-In

Versions are available for both Macs and PCs. Installation is straightforward. Simply copy the program into Photoshop's subdirectory called Plug-Ins and you're in business. Though the program is very easy to use it's definitely worth reading the well written documentation. It is provided as a PDF file and can be read on-screen or printed out.

There are two versions of the program, Color Mechanic and Color Mechanic Pro. The Pro version is the one to get. It costs $49.95 and is able to handle 16 bit as well as 8 bit images, and also CMYK files. The basic version is $29.95 and can only handle 8 bit RGB files.

Both files are available for download and are fully functional without payment, except that you can not save your changes. Still, you can experiment to your heart's content and decide if this program is for you, without cost. At any time afterward by purchasing a password online you unlock the file that you previously downloaded and are then free to use it fully.

Color Mechanic is available for both Mac (PowerPC only) and Windows, and requires Adobe Photoshop 4.0 or later or Photoshop Elements. Processing 16-bit RGB or 16-bit CMYK images with Color Mechanic Pro requires Photoshop 5.0 or later.

Note that Color Mechanic doesn't work on a separate layer, but directly on the image itself. You may therefore wish to save a separate version of your file before finalizing any adjustments done with this program.

Full Disclosure

Color Mechanic is published by Digital Light & Color. The president of this company is Jonathan Sachs, a talented photographer and an even more talented software designer (he originally wrote Lotus 1-2-3)

More to the point, Jonathan is a friend of mine. Notwithstanding, if Color Mechanic weren't worthwhile I'd either say so, or I'd simply not review it. But, Color Mechanic is a beautifully designed program and is very useful indeed. I can recommend it to you wholeheartedly.

April, 2002

Photoshop User magazine has now awarded it an Editor's Choice award for 2002 to Color Mechanic. They say, "This plug-in makes enhancing photographs ridiculously easy and quick. Besides saving loads of time and the hassle of using masks, designers can also "lock" any color so that when a close-by color is changed, the effect is restricted to just the tonalities and colors you want."
