Face Time with the D800E

As you know I'm not a people person...I mean people photographer. Occasionally I do shoot people when I'm out and about at an event like the Genoa (NV) Cowboy Poetry Festival I attended over the weekend. I went with some fellow photogs just to have fun. Usually I take my point-and-shoot memory camera on fun outings. I call it that 'cause it helps me remember where I've been and what I've done.

Since I'm still playing...eh...working with the D800E I was anxious to see how it would preform with people and clothes so I took it instead of my p&s. I'm happy to report I found no moire'. I'm also happy to report that I'm still blown away by the results I'm getting from this new film; 36 megapixels of low noise and maximum detail.
Check these out!

These images were shot at ISO800 with the 70-200mm Nikon Zoom 2.8 VR @ 200mm handheld. Both images were shot in FX mode, full frame 24x36mm. Detail from the full frame image follows each:

More Results E v nonE

We left off with me being pretty satisfied that the D800E is a little sharper than the D800. Little is subjective. I think the larger the print, and I mean really really large, the benefits of the E become more apparent and useful. If your a pro shooter and your images are on billboards the E is the only way to go! Or if you like to crop the * out of your images...

Let's move on to my next big question: How often will moire' crop up in my typical shoot? As you know I'm a wildlife photographer and for me wildlife includes everything in nature, but mostly things that go bump in the night (and day). I love to shoot landscapes, abstracts, and macro, too, and I love to make huge prints. So will the E or the nonE be the best choice for what I do?

These tests and images were done with the E unless otherwise stated.
Initially I was having a hard time finding the usual suspects, eh, subjects. Birds are a little scarce in the high Sierras right now and the ones that are flittering around are not very cooperative. As I was doing my sharpness test a robin appeared not too far away but in the shade. Okay, I shoot in the shade, let's have a go at it. Here's the original shot:

A little dark but I took a look at it in LR4 anyway. I zoomed in and thought I saw moire' in the gray feathers! So I tweaked a little and I did, I did see moire'. To make it obvious I increased the vibrance so you can see it too:
Exposure  +.45 and opened shadows a touch.
On the following image I increased Vibrance a lot so you can more easily see the moire'

Okay, now I'm a little nervous. I didn't expect this. I have been reading a lot on the web how moire' usually only occurs if there are grid type lines like you'd see in machine woven cloth or window screens. Feathers have been a controversy. Will moire' show up in feathers? How often? How intense?

Okay Jim, slow down, this is only one bird, and it's a robin. Nothing against robins mind you, they're just not in my viewfinder that often. I like large birds like geese, ducks, swans, egrets, herons, and birds of prey like Eagles! of course, Eagles! What's going to happen with Eagles? I don't know. But I do know what happens with this goose:


Whew! Not much, this goose looks good. No sign of moire'. I made a few images but not enough and with not enough variety of birds to be conclusive, I will keep shooting. I'm also thinking that the shade may have something to do with it. Is moire' more evident in shadow areas? Will bright sun reduce the chance of moire' in bird feathers? Will I have to shoot all my birds in bright sun? or will I opt for the D800? Stay tuned...
