[80] It may have taken 20 sheets or so to figure out the exposure index and how to shoot in camera, but it was well worth the trial and error.
This has been a great film to cut my teeth on as I delve further into large format.
I use d-76 to develop but have also found a lot of data for other developers as well.
Great film and a great price.

[80] Slow, but ultra-fine-grained - this is the film I choose for my b&w still-life's! I will also try shooting portraits on it. I usually rate it at the box ISO of 25 and send it in @to have it processed in to b&w slides . . . they always come out BEAUTIFULLY!!!Now that B&H is selling 25-sheet boxes, it's even more affordable.

[25 Sheets] This is a great deal for anyone wanting to try out large format without going broke. I shot this film at ISO 3. The final contrast depends on the developer and technique. If using D-76, dilute stock solution 1:4. With Dektol, dilute about 1:10 or 1:20. With Quintol, try 1:10. The film is not sensitive to safelight, so it can be developed by inspection. If you dilute Dektol too much, you will get film fogging. If too concentrated, the contrast will be too high. I have read that pre-flashing this film can make it behave almost like a normal film, just do a google search on this. The final grain size is very sensitive to developer type. D-76 seems to produce the finest grain, but I still need to test with 1:4 dilution as recommended in some literature. The attached negative was developed in Quintol 1:10 (paper developer). The emulsion is very sensitive to scratching, so be careful when handling it. The other ortho film option is Royal Regent hard dot film, about half the price of this.

[80] Watching my image develop under my safe life was the coolest experience. My scans look fantastic and it was easy to remove dust while loading under my safelight. This film is highly underrated.

[80] It's great that Ilford and B&H are still providing this high-quality ortho film. The quality is still excellent. For those unfamiliar, ortho film is similar to conventional medium-speed, continuous-tone B&W films for pictorial photography, except that it lacks the dye that makes the film sensitive to red light. Ortho film can thus be handled and processed under a red safelight, which is especially useful for folks new to the craft. It also allows one to develop by inspection, getting exactly the desired density and contrast. Note that the lack of red sensitivity causes a peculiar rendering of some subjects, especially skies, similar to many 19th century photographic processes. One word of caution: Some safelights are less safe than others. You'll want to perform a fog test of this film under your safelight to make sure it's safe. I found that my safelight, which is a bit orange and much brighter than needed, did badly fog this film until I added a baffle to cut the brightness.

[25 Sheets] I have purchased this product use with a Lensless Camera Company 4x5 camera that I purchased from BH. This is a fabulous pair. The film gives a wide range of gray-scale. In relative terms of a 'normal' film, about plus or minus two full stops. Even thin images have a great amount of usability. I personally scan the negatives and have digital prints made. The developer I use is IL-11 dilute and Ilford Rapid Fixer, both from BH. Processing can be done, as if a paper, in trays using a RED safe light. At about 30-40 films processed per liter, the cost per negative is about $1.35 (film+chemicals)

[25 Sheets] Litho film; for darkroom laboratory work. As expected this is a high contrast film. This is an orthocromatic film, and as such can be handled with red safety light for darkroom. This emulsion can also provide mid-gray depending on the exposure and the chemical process. We have used it to make some enlargements from 35mm and medium format black and white negatives with good end results

[80] I use this in a 4x5 studio camera to shoot wide open portraits, while it is high contrast, under flat lighting in a studio it sings. You cannot beat the price, and developing in print developer by inspection under a normal safelight is also fantastic.

[25 Sheets] This film is wonderful, can be process whit a red light. The film is perfect its like to be back in the 50'.....I use it in my Graflex and my Harman pinhole....

[80] If you like paper, slow film and/or ortho emulsions this stuff will become a fav. It's also very cheap and you can process AND loading under safe light.
