Steve, Rollei IR400 with a 25A filter doesn't look much different than any other panchromatic film with a 25A filter. It is an expensive film (10 bucks a roll last I shot it). I wouldn't bother using it unless it is with heavier filters than a 25A. It is not unique unless you use it with an opaque filter, or a near-opaque one like the R72. Without a heavy filter, it might as well be T-Max in the camera, IMO.
HIE, on the other hand, definitely looked like an IR film when used with a 25 or 29 see-through filter. That was HIE's greatest strong point IMO: it could be used hand held with IR-looking results, and without having to shift focus.
I agree. I would have to get a stronger filter and the cost of the film ... excuses ... but I would rather work with my 4x5s and learn large format in more depth, use the Hasselblads for my serious [sirius] work, and 35mm for traveling light when I what I am doing is not centered around photography than shoot IR. There are too many other interesting things to do.
Warning!! Handling a Hasselblad can be harmful to your financial well being!
Nothing beats a great piece of glass!
I leave the digital work for the urologists and proctologists.
