Greg Gorman's B&W; conversion technique
Tuesday November 18, 2003
by Greg Gorman

Greg Gorman shares with the Imaging Revue subscribers, a technique that finally allows him to shoot color and still get the B&W; effect he desires. Designed by his retoucher Rob Carr, this step-by-step tutorial will show you a great new way to not only convert color to B&W; but add color toning as well! Please refer to the forum thread that got this discussion started.

AuthorSubject: Imageprint (Lite) 5.6 User Evaluation   [Go to Bottom of Page]

I finally took the plunge and bought IP for Epson 2200. First of all, the B&W; is really stunning. I have never had much interest in B&W;, but after seeing the output with IP, I decided to print a few photos (converted with B&W; Pro from color transparencies). The prints truly look neutral no matter what the light source!
This really sparked my interest in B&W;!

This evaluation involves the use of IP for color prints, my main interest. I selected a test image of the old mine at Bodie a friend took when we were there a year ago. This image was chosen because I had trouble getting the colors to come out right when I printed it for her and was never really satisfied with the output. A jpeg of the test image can be seen here:

I will refer to specific parts of the test image in my comparison, so you may want to have a brief look. Photos were printed at 6.5 X 10 inches on Epson Premium Glossy and compared under Just Normlicht Colormaster Duo lightbox. Custom profiles were created using Eye-One Pro and Profilemaker 4.1.5 with settings 1440 DPI, Large, Paper Gray, GTI lightbox. Stock IP profile was "EDAY", so prints were also compared in diffuse sunlight to make sure that the stock profiles were not at a disadvantage due to the light source (the differences were a little less dramatic, but still clearly
there).

Here are the results, listed from worst to best:

1) IP Stock Profile: I must admit that I was immediately put off by the color of the
sky. It had too much magenta and looked completely different than any of the
other prints. I pulled out the original transparency just to make sure, and yes,
the blue generated by Profilemaker for all of the other profiles was MUCH closer
to the original slide and to the image on my calibrated monitor. The second
thing I noticed was that the prints appeared identical using perceptual and
relative rendering intent! The print was generally pretty close in color, but
there was a slight lack of red noticeable in the roof in the lower right hand
corner and in the scrub brush on the hillside behind the mine, and in the gray
building itself. Since a representative area of the gray building measured
64,0,1 to 64,0,-1 with the eyedropper in photoshop, I knew it should print
neutral. Measurements taken from the print for this gray area were:
58, -3.5, -3.5 for Stock IP Profile; 62, -1, -2 for Custom IP Profile
converted with relative intent and BP compensation; 64, -1, -3 for Custom IP
profile converted with perceptual intent. Thus, the measurements
agree with my subjective impression that the IP print had a little too much
green. Looked fine by itself, but not as good when compared to others.
(Rating 8.5)

2) Custom profile made through Epson driver: Similar to the IP Stock Profile, but sky
was MUCH better. Shared slight lack of red in building, scrub brush. Did the
worst at reproducing the roof in the lower right--too yellow and too dark.
Also, had the two pieces of plywood on the building lower right too yellow.
PS This profile would have been the worst, except for the awful sky color of
IP stock profile. (Rating 8.5)

3) Custom profile made through IP:

Perceptual Rendering - Stunning output, colors spot on. The best separation
of colors in red roof in lower right by far. Building color looks comletely
neutral. Scrub brush on hillside has proper amount of red. Vertical rusted
pipes from roof produced with the right amount of red (lacking in other
prints). Just a whiff of green missing from scrub brush to left of building.
This is what I saw when I was there! (Rating 9.7)

Relative intent with BP compensation - Different from perceptual but equally
good. A bit more "punch" to the image. Green in scrub brush to left of building
more accurate. Separation in red roof colors lower right much better than IP
Stock Profile, but not nearly as good as perceptual intent above. Vertical
rusted pipes with a little less red, but much better than IP Stock Profile. Gray
building color with just a hint too much green, but again much better than IP
stock profile. (Rating 9.7)

My conclusion:

Most accurate match of soft-proof to print: Custom profile made through IP
Most pleasing rendering of image: Custom profile made through IP, your choice
of perceptual or relative intent

I did this test so I could see whether IP was worth it for color, and whether I would feel the need to spring for IP if I get the Epson 7600 or (gulp!) the 9600. If you want stunning color, in my opinion the choice is clear: IP with custom profiles.

I hope others will benefit from this report, and share their findings as well. This test was done on only one image, and an image with different color might turn out quite differently.
