I thought about writing a summary of the origin and significance of the Retro IR Sensitive films as an aerial mapping film. But then I found an excellent history/summary by My Favorite Lens reviewing the Retro 400S. So check it out…………
Now we take up Part II of our IR Sensitive Film Tests. Here a comparison of Rollei Retro 400S and Ilford SFX-200 (My Standard). We again applied the IR 695 filter to both rolls. We know from our previous experience that this filter adds contrast to the Retro-films. So let’s jump in………
Images on the left are from SFX-200 and on the right from Retro 400S:
We ca see the obvious difference in Contrast. But it this first image it works.
Above, the contrast in the clouds for the Retro 400S makes it more interesting to me.
In the four images below,the lighter contrast (SFX-200) allows iu to see more detail.
Agai, here I think you choice my depend on personal aesthetics. There are qualities I like in both images.
S, we have determined in both cases that perhaps the Retro Films don;t really need IR-filter enhancement. So for our next test we are going bare. I’ll be comparing the Retro 80S with no filter to the SFX-200 with the IR 695.
