More Infrared Experiments Rollei IR 400 in Ars-Imago Fd

Rollei IR 400_Ars Imago 001

As you can see, the experiments with infrared (IR) continue. As mentioned in the previous post, during the last photographic trip, besides the Ilford SFX 200, I shot a roll of Rollei IR 400, with the aim of developing it in new  Ars-Imago Fd. A couple of days ago, I had enough time to do it and as first thing I had to find a starting time for development, given that it was a “first time” and there were no data about in the data-sheet.

Infrared – Another Test

Rolleiflex_Sfx_001

After the first (successful) attempt with infrared photography (IR), I immediately wanted to try it again and so, taking advantage of a beautiful sunny day, I shot other two rolls with my “usual” Rolleiflex. The first, a Rollei IR 400 again, I have yet to develop. As a second, this time I used the Ilford sfx 200, to assess any differences in performance with the previous one.

Infrared: the amazing invisible realm

 IR400_001

When we venture into the mysterious field of infrared photography (IR), we enter the realm of the unknown, or rather of the invisible. The human eye, in fact, is not able to perceive the luminous radiation of infrared above 750 nm. And it is beyond this threshold that infrared radiation vibrate. What is therefore beyond the insuperable limit of the visible? Since the 30s of last century, the photographic technology allowed us to find it out, creating emulsions with appropriate sensitizing elements to these frequencies.
