How would I be able to take a picture that looks like this?
I started entering portrait photography, and I found an image I attention. Http: / / c2.ac-images.myspacecdn.com/images02/70/l_4bb81b6bd9d346cb90a3090595f76441.jpg me to achieve something so close. Any advice? Should I use a diffuser? This is the team got so far, Nikon D40 18-55mm AF-S 55-200mm AF-S 55 mm f/3.5 Micro (manual focus) 50mm f/1.8 Series E (manual focus) SB-400 Flash Thanks in advance!
N diffuser, (unless you use a beauty dish with a sock) hard light directly on to the left slighty. The size of the light source is important depending on the size of the individual. (I use a beauty dish) + snoot light just behind it to frame in the background. lens wider angle, plus use a full frame camera which is what was used in the capture of reference. Not required, but I'm just being specific. Colors can be adjusted in Photoshop hardlight desaturated layer above the original and / or tungsten whitebalance camera using daylight strobes balanced style to create that color. This can get you started.
