Brandywine Park, De in Infrared, Canon 20D

Who said it can’t be done? Last Saturday I went to Brandywine Creek State Park to experiment a little with Infrared Photography (see my other three pictures starting here) Those three were taken using an old Nikon CoolPix 950 and Wratten filters (87C, to be precise). This photo here was, on the other hand, taken with a Canon 20D with a Sigma 15-30mm lens, which has a back end slot for gelatin filters, and I used a Kodak Wratten 89B filter. I understood you could not take IR pictures with a 20D but I guess all is in the patience you put in something to achieve what you want.

ISO: 400
Exp: 6sec.

The original picture, as it came from the camera, is to your right (click on thumbnail). Picture was cropped, converted to Lab, discarded channels A and B and you are left with the Lightness Channel to work with. A Level and Curves adjustment did the rest.


Finn’s Point Cemetery

Interesting ghosting effect I discovered to the right, alongside the monument. This was only visible after I adjusted the “Levels” in Photoshop. I guess it was a bounce reflection from the IR filter to the lens due to the long exposure (2.0 Sec).
Picture was taken in color, converted to LAB color space, deleted the A and B channels, adjusted Levels, and used “Shadow/Highlight” adjustment to fine tune the midtones and final contrast.
