My experience is the same as Evgeny's and John's; HP5 pushes better than Delta 400. I have an 8x10 from HP5 pushed to 3200 ASA. The grain is remarkably small, but the tonal range makes it a bear to print. However, this film allowed me to capture an image I would not have gotten otherwise.(posted 9362 days ago)If you're having grain problems with HP5 at 400 ASA on 8x10 prints you might want to look for other reasons. I use a cold light head on my enlarger, which tends to keep the grain under control compared with condensor heads. However, no 400 ASA 35mm film has given me what I consider acceptable grain larger than 8x10. Maybe we're just picky. I've made beautiful 11x14 prints from 35mm T-Max 100.
