Pellicola Ilford Ortho Plus 80-120

I wanted a slow-ish BW film for pinhole photography that would work well with outdoor/nature type subjects. I have been using it for 6x9cm images in my Ondu pinhole. I often offset the baffles in the Ondu to give a "rise" effect when used in portrait orientation. This also means that the inherent vignette on the extreme of the neg is usually in the sky which looks great. I've been very pleased with this film for this purpose. I get a lovely range of tones in the image (although I have to up the contrast in post, but this is the same for all films I have used with the pinhole). It also works well on architectural shots, even interiors. The church interiors had a 30 minute exposure, commercial dev and scan.

The film is nice and sharp, the grain is fine and has a pleasing texture to it when visible.
I have had a very odd experience with it more recently when shooting some portraits, in my example below you can see there is a slight glow, which looks not too dissimilar to infrared film stock.

The underside of the boat in one of my images was red. This is where this film really shines.

Overall I like the film and will be using it again in the future!

Here's a sample shot developed with DF96

My first time using Ilford Ortho Plus.
First impression: the detail. It's truly good. Extremely happy with that.

I have something important I'd like to pass on regarding the exposure. I took a few varying exposures between ISO 80 and ISO 50 on a bright but overcast day, and developed as normal in ID11. Usually a little extra exposure can help boost the shadows on a lot of film but I really don't think it's necessary with this one. I really do think it's a genuine ISO 80 film and rated quite accurately. This sample picture was taken at ISO 64, and though the detail is incredible, the shadows are starting to lose their depth.
In my experience with the film, I'd say to aim for ISO80 or 1/3 of a stop overexposed if in doubt but no more.
If it was a sunny day then my experience might have been different, so it would be interesting to see other people's opinions on this film too regarding sunny weather.
Overall though, I'm extremely happy. Very fine detail and a nice look. Best suited to individual subjects or landscapes, where a certain look and high detail is required. Would love to try again, and keep at a firm ISO 80.

I’m no great fan of Ilford films, but I find Ortho Plus terrific! It has a tonal range that gives a wonderfully nostalgic feel. I am protanopic, that is red colourblind, so in theory orthochromatic film should represent the world I see quite nicely. I cannot say to what extent that has ‘coloured’ my opinion.

Unlike say Rollei ATO 2.1, which is orthographic and very high contrast, Ortho Plus seems to have very good latitude. An accidental overexposure by three stops proved perfectly printable. I develop it in Rodinal, 1+50 for 15 minutes at 20c. Some great films seem to have come and gone in recent years, so I can only hope this excellent film is around for some time yet!
