Re: BW Developers-Grain differences
You're talking about different enlarger light sources right, diffused, cold, etc.? Care to expound Mike? Norm Mike Johnston wrote: No. It's the enlarger. The difference in perceived grain between a highly collimated light source and a true diffuse light source is extremely significant. Most enlargers are somewhere in the middle. This is one thing that causes differences in reports of the graininess of films. Some people can say Tri-X has golf-ball grain and others can say Tri-X has extremely fine grain for a fast film and both can be right. - This message is from the Pentax-Discuss Mail List.

Re: BW Developers-Grain differences
Norm, I'll send you an article file off list. Basically, only those with access to a variety of enlargers really understand the rather large differences that the enlarger light source has on the appearance of bw films in the print. I once made enlargements of the same two negatives on a Saunders 4500II and a Leitz Iic (magnificent machine, but a bit like driving a Duesenberg to work--I wouldn¹t want to have to print on it all the time). I wish I could find those prints--the differences were remarkable, and highly instructive. --Mike Norm B. wrote: You're talking about different enlarger light sources right, diffused, cold, etc.?

Re: BW Developers-Grain differences
Not sure about the enlarger types, I have a Durst 606 at home, the school has besselers, they are huge and have bellows that the negative carrier goes into, they are brand new,I am not sure of the model number. - Original Message - From: William Robb [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, October 27, 2001 1:00 AM Subject: Re: BW Developers-Grain differences - Original Message - From: RH Subject: BW Developers-Grain differences Hi all, I have a question for all of you B/W chemical experts. I am printing pictures at home and at school using enlargers both with 50mm lenses. At home I use ilford universal paper developer and at school they use some kind of kodak developer. Now,I printed some pictures at home of the same negative I used at school and there is noticeably more grain in the picture. Will different developers do this? Is ilford a large grain developer or something? Could it have anything to do with the enlarger, at school I have a much larger one, but when focused on my 8x10 paper, both my one at home and the one at school are roughly the same height off of the paper. I doubt if the developer/paper combination would cause this. You didn't mention if you are using the same paper at home as at school. There are a couple of other things more likely. First, are both enlargers the same type of light source? A diffuser source will show less apparent granularity than a condensor source, all else being relatively equal. Also, you could also have a much better lens at home than what the school has. William Robb - This message is from the Pentax-Discuss Mail List.

Re: BW Developers-Grain differences
you also need to check what grade paper you are using. i forgot those things now - i used to do lot of bw printing some 15 years back, however, one thing is sure - you change the grade of paper, you get totally different picture. grade of paper, dilution of chemistry, freshness of chemistry ... all count. some points from my side. anand From: RH [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: BW Developers-Grain differences Date: Fri, 26 Oct 2001 23:57:13 -0400 Hi all, I have a question for all of you B/W chemical experts.
