So, I made some test shots inside my house with ORWO 100 at EI 100. Cut film in half. Developed one half in HC-110(B) 7.5 minutes. Developed the other half in Rodinal (1:50), 16 minutes - both at 20 degrees C Looked at the film in my microscope and then took picture through the microscope with digital camera. Hee's the Rodinal shot: http://www.apug.org/gallery1/showimage.php?i=75798&c=502 Here's the HC-110 shot: http://www.apug.org/gallery1/showimage.php?i=75797&c=502 The grain is certainly more apparent in the Rodinal image. I think I can convince myself there's a wee bit more edge sharpness as well. I also developed some ORWO 100 in Diafine...and I gotta tell ya, looking at all these negatives side-by-side, it's a graphic explanation why I need high-contrast filters to print negatives developed in Diafine. The HC-110 image taken in the microscope is a little on the light side, but the HC-110 negatives looked quite nice, as did the Rodinal ones. Haven't gotten around to printing them yet - I have to commandeer the hall bathroom for that!
