You're simply underexposing for the development you're giving. I get EI 320 for HP5+ in ID-11/D-76 1:1; many people get EI 200-320 for this combination. Ilford really dropped the ball with their recommendations for Delta 3200; using their specs for ID-11 gets a slightly contrasty EI 800. So for your HP5+, try EI 250 or so, and for Delta 3200 try EI 1600 in Microphen 7'/75F.(posted 9138 days ago)
