Here’s a quick shot from my latest studio shoot. Eboh and I were helping Nikki update the images in her porfolio. This image was lit from the front with a softbox that included a blue gel filter. Another softbox with an orange gel was angled from the side.
Studio shoot: Nikki (blue) 645D with 67 105mm lens
The colored gels create an interesting look. Reminds me of the lighting in some of the C.S.I. crime labs.
Model: Nakita Nedd
Lighting: Eboh Ajeroh

The pic does have an atmosphere.
It seems the Pentax 67 lens on p645d works fine. Still wonder the resolution is up to the bar of 645d.
