I like to "sketch" images from shoots. These are basically just quick stylistic treatments that aren't necessarily how I imagine they'll be used by the client, but nevertheless provide a good way to explore different "feels". Increasingly, I am previsioning shoots with different post production styles in mind. (Look at me getting all artsy!)
Most often for these sketches I'll use Analog Efex Pro 2 by Nik software (recently purchased by DxO). I rarely save recipes because I want to avoid being in a rut, utilizing the same "tricks" time after time. Having said that, I do have a few basic recipes that I start with as a base and I will individually salt to taste each image afterwards.
Big thanks to assistant Steven Wesley for humoring me, arriving 2 hours early to scout the location and listen to me mutter, "it's gonna rain any second now..." Also big thanks to Erin Otwell at Science News for the assignment and for being so open to creative interpretations on this and the first two parts of the assignment.
Tech specs, because people ask: All of the portrait images were made with a Canon 5Dmk4 with the amazing Canon 85mm f1.4 IS L series lens, EXCEPT for the first image, which was made with Sigma's 35mm 1.4 ART lens. Both of these lenses are really really pretty in their own way. Lighting was via a Profoto B1 and their collapsible 22" beauty dish. The latter of which, while it feels flimsy, is a pretty nice little modifier. All images put through CaptureOne Pro and processed in Nik Analog efex Pro 2. I don't think any of these ever hit Photoshop.
