First attempt at infrared portraits using efke IR 820.

This is the result of trying to salvage an extremely underexposed negative through scanning. The initial preview showed pure black. I brought out the image by pushing it as far as i could using levels and curves in the Imacon scanning software.

The specs are not grain but minuet amounts of dust that wouldn't usually be scene in a normal scan. Bringing the image out brought the debris out as well.

I don't have any IR filters, so I shot in the dark using modified Vivitar 285HVs, one with a double layer of processed unexposed 35mm Ektachrome (reducing it to about a 1"x2" flash area) and another with a red gel folded over 16 times (acting also as a diffuser).

I metered at 100 iso based on the film's data sheet (25 iso when using IR filters).

The gelled flash produced more visible light metering f/3.5 at about a foot, while the chrome flash produced more pure IR light metering f/8 at about a foot, both at full-power. Though, I'm not entirely sure how well my Sekonic L-358 would meter pure IR light.

I processed in D-76 at 20 degrees celsius for 8 minutes. My chems should be good, but it's possible they could be getting weak.

I'm not sure exactly where everything went wrong.

Next time I will meter at 25 iso. I will use sheets of processed unexposed 4x5 Ektachrome (instead of 35mm) with larger more powerful strobes and/or directly on the lens as a makeshift IR filter.
