Title: GREATER SAGE-GROUSE - FAMILY PORTRAIT, DAWN
Species: Greater Sage-Grouse (Centrocercus urophasianus)
Photographer: James McIntyre
Date: April, 2002
Location: Morgan County, UT
Equipment: Canon EOS-1VHS/EF 600 mm F/4L IS USM + 2.0x I TE/Gitzo 1548 + Wimberley Head
Film: Fuji Provia 100F
Evaluative Metering: +1/3
Scanner: Nikon LS-2000
Scanning Software: LaserSoft SilverFast Ai v4.0 (IT8 calibrated)

Every spring, as the snow begins to leave the high desert country of northern Utah, one of Nature's most remarkable exhibitions may be observed. Each day before dawn, dozens of Greater Sage-Grouse assemble on their ancestral lek to begin their traditional courtship and mating ritual. Grouse cocks raise their spiked tail feathers in a crownlike fan, throw their heads back and inflate the large air sacs on their white-ruffed breasts. Suddenly they clasp their wings forward in a rapid motion and emit a loud two-note descending call, "BOOL - DUP!", that can be heard a quarter-mile away. This display is repeated again and again.

Only a few dominant males are successful in attracting females. Once having mated, the diminutive hens retreat silently into the sage brush to raise their broods of chicks as single moms. A few hopeful bachelors linger briefly after sunrise, facing off and staging mock fights. Then they too vanish into the brush to avoid the talons of hungry Golden Eagles.

An hour after dawn, there is no trace of the remarkable event just witnessed.

Looks like this could be a nice shot but the photo has almost no contrast. Hope you don't mind I took the liberty of correcting the image and removing the blue cast. The image has been removed from my hard drive:

This has a Grant Wood feel to it for me. :D I love the poses and the birds positions in the fame. E.J.'s repost helped with the contrast issue.
Otherwise this is excellent.

james, Love all the colors and textures in this scene. You had a tough lighting situation here, If you could get the sun behind you, there would be less contrast issues. A great photo.

You've heard the comments. It's a scene I'd love to photograph.

Great scene that I don't think the scan does justice to. I'd love to see the slide. Well seen.

I, too think that you must have lost a great deal in the scan. I think it's a very interesting image.

Thanks to EJ and all who commented on my GSG picture.

I think most of the perceived contrast and scan problems were monitor-related. When I edited the original pic in PS, I was using a ViewSonic PT813 aperture-grille monitor calibrated with Adobe Gamma at Gamma = 2.2. If you were viewing with a MAC with Gamma = 1.8, then the picture would indeed probably seem to lack contrast. I actually boosted the overall contrast slightly in PS with an S-curve (59/64,128/128,197/202). I thought anything more was too much.

Also, I had already desaturated the blues in the birds and foreground shadows: -50(150/180-210\240). I think this was a problem with my old Nikon LS-2000 scanner. A global correction would have been better in retrospect. But there is not much if any blue in the background area, e.g. above the cock's head, so the claim there is an overall blue cast to the picture is, I think, unfounded.

I 've just recalibrated my monitor with ColorVision SpyderPRO with Optical. Now the picture in PS lacks a little contrast with the original curve compensation, but still looks quite good - to my eyes. The main problem with the original was too low a black point setting. I also checked the PDI reference target again. The old calibration was pretty darn close. With the new calibration, a very slight magenta cast was removed. That's about it. The biggest difference is that I can now see NatureScape pictures like Harvey Edelman's fine Reddish Egret picture as they're intended to look. My old monitor profile was apparently too contrasty.

ASAP I'll rescan the original slide with my new Nikon 4000 ED and repost.

But I've gotta make a final comment:

Aaargh!!! EJ, what did you do to my beeyootiful grouse picture? Was that some kind of weird Halloween joke? Your version looks absolutely garish on my monitor! I've never seen an ORANGE sage-grouse! I'm calling your version EJ'S NIGHTMARE ON THE SAGEBRUSH STEPPE.

So I'm gonna call you out in Soccorro in November! Meet me at the BLACK DOG CORRAL at HIGH NOON and be packin' your monitor. We're gonna shoot it out. Loser buys lunch. :x
