One consideration nobody has mentioned is that you are using what is essentially an Artar design lens - the APO Nikkor is a process lens. The artar consists of 4 elements in 4 groups. That means...

Try using ordinary automotive brake cleaner. It is designed to cut grease (or old lubricant) and evaporate without residue. Will it affect cement at the edges of cemented lenses?...possibly, but it...
No. I started using polycontrast papers in 1970. Pyro has been around as a developer for at least 130 years, probably longer.
I wrote about "dual purpose" negatives in my first View Camera article...
Mr. Layton,
You will find THE definitive treatise on soft focus lenses at this link - http://research-repository.st-andrews.ac.uk/handle/10023/505. The author is Russell Young PhD. He received a...
Anyone anywhere considering meeting someone about an ad on Craigslist, please read the news item at this link - http://www.ohio.com/news/akron-man-is-third-craigslist-shooting-victim-1.248539. I...
Along the French Broad River in Tennessee in the fog one the morning after intense thunderstorms during the night. Peaceful and quiet.
Dear Lord Almighty. You need help.
Ken,
Fair question, sir. There are very few topics discussed here or questions asked that haven't been asked and answered a dozen times on this and other forums in the past 10 years. Threads...
Right on the mark. Years ago APUG became useless and irrelevant. This forum is approaching the same per "Once's" comments and I have only been here one year - may not stick around much longer. ...
I had the same problem with a 13" version last summer. A web search sent me to this thread which happened to be on this forum - http://www.largeformatphotography.info/forum/showthread.php?t=47096...
You searched? Really? Google? Keyword <ilford ulf>. It is right there in the search results. Didn't try very hard.
It's a beautiful thing. The freezer is well-stocked. Enjoy!
Maybe this is heresy, but has anyone here considered that this thread might be serving the purpose of increasing selling prices of these lenses?
I should probably also add one more comment for clarity. The minimum amount of developer required per square inch of film will vary with different films and is directly related to the silver content...
Ken, one more note to your comment about volume - " if you are exceeding or stretching the capacity of a given volume (too many sheets, insufficient volume), then it will take longer to develop". ...
On the contrary, I am very interested...enough so that I took Tillman Crane's soft focus workshop in September down in Floyd, VA...and subsequently picked up a Kodak 405. There is much good...
In my humble opinion, changing 20x24 film in the field is very doable. For 12x20 field work, I used a Harrison jumbo tent with the ULF "wings". It spreads out to more than 72" from pocket to...
Richard Ritter. I just had him overhaul my Pentax Spotmeter V that was 22 years old and was just plain worn out - something about 20-30,000 uses.... Good as new.
Looks like this thread has become a secondary ebay listing site. There is some good information in here, but seriously, 85 pages and 841 responses????
Thank you. This kind of response is the difference between real life experience and reading spectral sensitivity graphs in product specs. I have four large Gralab 300 timers hanging above my sink's...
Here is an approach I recently used myself for some FP4 negatives that received two stops of overexposure - I didn't have a choice at f6 using a Verito outdoors even with an overcast sky. Mix up a...
Calumet Photographic, Chicago, IL. Two months ago, I bought 200 rolls of TMX - in stock and at my door in three days. Earlier this year I ordered 150 rolls - in stock - same delivery time. They do...
I like Dave Wooten's comment the best! Once you get beyond a 24" lens, depending on the length of your arms, it involves a well worn path between the back of the camera and the front of the camera...
Pyro image stain is more archival than the silver. Attached are two images for illustration. The first is a scan of a negative on which virtually all of the silver is gone. The negative was shot...
