My lighting was two 1000W constant lights with white umbrellas...both at 45 degree to myself and the camera in between them.
I shoot in RAW...so I take the images in BW then convert the chosen images to colour and then mask out everything but the nails from the colour version...allowing the BW to show through beneath.
Very little is done to these images...mainly a slight contrast adjustment, crop, resize and USM.
Wow! This photo really caught my eye. I love the selective desaturation; in my opinion it 'makes' the image. Superb composition and focus. I really like the creative border as well. Going in my fav's right now.
