Strobist info: SB-26 @ 1/16 shoot-through umbrella behind and above camera for fill; SB-600 @ 1/8 CL above and to the left of model's face shot through a very tight snoot. Finally getting serious about retouching, I've been watching Chris Orwig's portrait retouching tutorials on Lynda.com. It's always best to try this stuff on yourself first, in my opinion, because you never know what you're gonna get. The retouching steps I took were something like this (and not necessarily in this order): -Cleaned up blemishes and fly away hairs on a new layer. -Reduced eyelid shadows on new 35% opacity layer with patch tool -Selected just the skin and made a new layer and a copy of that. -Surface blur on the bottom skin layer and lowered the opacity to smooth out the skin. -High-Pass filter on the top skin layer & set a blend mode to Soft Light to bring back some skin texture. -Merge layers and copy, then unsharp-masked that (which I definitely over-did - partially on purpose). -Added Highlights to hair by making a new soft light layer on top and painting with a white brush at 15% opacity. Brightened eyes in a similar fashion. -Merged layers and Copied that. Set copied layer to a blend mode of Multiply at 35% opacity to create some more dramatic shadows. -Shaped the face a bit by making a soft light layer, filling it with 50% grey, and painting it with black for the shadows and white for the highlights. Smoothed that out with Gaussian blur. -Made some adjustment layers to correct the tones, exposure, and brightness and desaturate it a bit. Brought up the exposure of subject's right eye. -Changed color of background by painting with a purple brush on a soft light layer (background was originally an off-white). -Added vignette with a large, soft black brush on a soft light layer. Gotta love the soft light! All told, it took WAAAY too long, but it was a lot of fun and I learned a ton in the process. Please have a look at the large version to see the details of the retouching. Comments welcome; let me know what I did wrong and right! (And yes, I know I should've shaved my 12-year-old whiskers off.)
Filter Splatter Cu
Filter Splatter Cu
Here is one way to kill a filter... get molten copper splattered on it. This is a dark red IR pass / most visible light blocking filter. We use them at work to take high speed video of large electrical arc events (arc flash). We got this one a little too close and it ended up with some copper splatter on it. This one still works but we quickly realized that a sacrificial clear filter was in order to save the more expensive 092 filter. Strobist: filter on a piece of white foam core. 580ex ii high camera right shot through a diffusion screen. 1/250, f/9, ISO 800, with the flash set to 1/16 (I think)
