White Atamasco Lily and Blended DOF

Here's another holiday flower. A white atamasco lily. This shot also uses three stacked shots to extend DOF.

http://www.thelightsright.com/files/...amascolily.jpg

I started in ACR 5.2. I selected the shots and then clicked on the Tools | Photoshop | Load Into Photoshop Layers menu item.

Inside Photoshop CS4, I used Edit | Auto-Align Layers with the Auto Projection option and then Edit | Auto-Blend Layers with the seamless Tones and Colors option. That stacked the layers and blended them.

After I stacked the shots in Photoshop CS4, I used the TLR Professional Sharpening Actions. TLR HRDC Capture Sharpening, TLR Clarity Enhancement. After recducing the photo to 1000 pixels wide and converting to sRGB, I used the TLR Web Output Sharpener.

This was shot under natural light with a Canon 1Ds MkII, Canon 180mm "L" Macro Lens, Gitzo tripod, Kirk BH-1 ball head.

The pistil for the flower extends well in front of the stamens. The stamens also varied in height. No way a single exposure, even at f/32 could get the DOF necessary when I was about 18 inches from the pistil of the flower. You'll see that even the pollen grains on the pistil are sharp.

Comments are welcome.

Mitch

Here is the result with 4 shots:

It is a big improvement with regard to the pollen on the white petals. I had to take the photo down to 12 x 8 at 240 ppi and 8-bits per channel for this. Given that I used +2 exposure compensation, I pretty well nailed the exposure and I am also happy with the color. So, I foresaw no serious problem with 8-bits per channel.

What do you think? A significant improvement, isn't it!

Cheers,

Mitch
