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.
Why not start the Year 2021 with some film tests………..
I had casually tried some Retro 80S on the drive home from Phoenix in 2019. But I wasn’t really planning on a comparative study and my image were not in pairs. So I decide to set-up a real study comparing Retro 80S AND Retro 400.S This is Part I where I will discuss Retro 80S.
The tests were conducted using 120 film and my Mamiya-7 cameras both with IR 695 filters. Ilford SFX-200 was my standard for comparison.
All of the SFX-200 imafes are on the left, and the Retro80S on the right.
In my first images from 2019, I had used a Dark Red filter for the Retro 80S. applying the IR 695 to the Retro 80S made it more contrasty than preferred. So I thin for an future use I would recommend using just a Dark Red Filter, instead of the IR 695 for the Retro 80S film.
