Ilford Ortho Plus

[Michael R 1974]

Anyone have any experience with this film? I'm particularly interested in its graininess. Ilford describes it as "fine grain" but I'm wondering how it compares to say FP4 in graininess, assuming it is developed to pictorial-type contrast in a standard developer such as ID-11.

Thanks
Michael

I have made negatives from the ISO 24 ortho Rollie for contact negs on silver with good results , I believe the Ilford product would be as tight.
We used HC110 for these negatives, At 20 x24 our digital contact print on Ilford Warmtone matches the enlarger print on the same paper from the same neg.

I cannot speak to ID - 11

I have never noticed a grain problem with this film and would think it quite comparable with FP4. Of course it depends on how you use it.

Thanks for the feedback. I'm going to order some and try it out for some masking stuff. I've mostly used slower ortho films for that, but wanted to give this Ilford film a try.

I've used a lot of the Ilford Ortho film and in terms of sharpness & grain it's on a par with FP4, it's an excellent film. We used it commercialy for copy negs and in terms of processing it behaved in a similar manner to FP4 as well, the only real difference was the film speed and spectral sensitivity.

Thanks for this, Ian.
