Ari,
What are the effects on the film emulsion that acetic acid would cause?

Ari,
Somewhere I read use a 1% or 2% acetic acid stop bath. If some guys are using just plain water for film, maybe I go to 0.5% acteic acid. Somehow, it seems better to have SOME chemicals in...

Distilled white vinegar is 5% acetic acid, mix 400ml vinegar and 600ml water, and you have 1 litre of stop bath.

The stuff is very inexpensive!

I have decided to stock up on P30 and Ilfochrome paper. I need to know the ratio of p30 kits to 20x24 prints in order to go about this correctly. I looked all over for the p30 kit insert PDF, and...

OK, everything I read tells me that Velvia and Ilfochrome is the pinnacle for color landscapes.

I buy a Toyo 45AII, three lenses, and everything a landscape photographer needs such as backpacks,...

I scanned a 4X5 slide, and it is 84mb. I tried to send it to Adorama, but 60mb is the largest file size they accept.

Any suggestions as to where I can send this jpeg file to get printed?

I saw with great pleasure that the Ilfochrome P-30 kit is being sold by B&H. However it is a 3 1/2 hour drive to N.Y. to pick it up, since they will not ship it!

What is the shelf-life unopened...

I wonder what the percentage of people on this site need reading glasses? I wonder if we are a bunch of geezers who are committed to the large format for "sentimental" reasons?

I bounced around a bit, but eventually downloaded a "free update" for the Windows 7. Things are working fine!

Once again, thanks everybody! Oh by the way, I explored around a bit and found the...

I was playing with my Epson V700 on my son's old laptop that runs Windows XP (40gb hard drive & 512mb RAM) it ran really slow, but it did download all the software that came with the V700, including...

How large a file should I reasonably hope for when scanning a 4X5 neg on an Epson v700? What is the "typical" size file printed from by a digital lab? What would minimum and maximum size files be...

NEVER NEVER think you hace a dumb question! I was glad you asked. I learned something valuable too!

If I still use 300ml/20X24 print on my Jobo with the 3063 tank with the solutions Larry suggested, it will cost $0.86/20X24 print in regards to chemicals. This will reduce my costs for a "three...

The Fujicolor Crystal Archive 20X24 is $2.00/sheet the Tetenal Mono PK is $6.00/sheet.

I cut the 20X24 into six 8X10's, so if I go through the process three times, it is $32.00.

I can't really...

Larry,
At this point I will follow your lead. Thank you so much for the effort and the web addresses!

Allen,
For the most part I use 8X10 to test time and filtration, and print to 20x24....

Thanks Sam!

However I get confused by the "adjectives": additive, starter, replenisher. I'm thinking these relate to some large automated processor. Or do I just ignore these descriptors, and just...

I have been using the Tetenal Mono PK RA-4 "kit" for my initial foray into prints from color negs. It is working just fine!

However, it looks as if I buy Kodak Ektacolor RA Paper Developer, 1...

Great success!

I bought a 24" Fiskars paper cutter and made my own 8X10's from the 20X24 Crystal Archive. I did the time testing, started @ 40M 40Y (it was very close) I ended up using 20M 40Y and...

Bob & Drew,

Thanks a bunch! After I posted my thread, I got on photo.net and found essentially the same info as what you guys gave me. The difference was that post was 5 years ago.

I hope this...

I've spent several thousand bucks on getting set up in 4X5 (camera & darkroom). I was playing with Kodak Supra endura on 8X10, and decided I was ready for 20X24.

I bought 50 sheets of Fujicolor...

OK, assuming the BS dry mount is better than the Epson dry mount holder. How much better (if at all) is the wet mount method over the dry mount method in the BS system?

And to put confusion to...

Steve,

Based on what you said I will buy it, and post back my opinion (as soon as the cold winter wind outside here in central Pa. dies down).

I have amassed a near complete 4X5 field outfit via ebay. I lack a center ND filter for my 65mm lens that at times the light fall off is annoying, however not as much as I expected after viewing the...

Joanna & Frank,

May God richly bless the both of you in the upcoming decade.

I thought I cleaned that glass as fully as I possibly could have, but because of your posts I looked closer. The...

I scanned 645 slides in the same area of the glass, and there was no problem! I also noticed some "white artifacts" on the negative scan that are definitely not on the negative. These are linear in...

I'm a neophyte. I scanned 4X5 color negs and get a thin blue line on the exterem left side. It does not happen with 35mm or with reflective copies. Anyone else have this problem? Any ideas? I'm going...

I did not find a guy with the electrical know-how to test the power supply. I bought a pristine Chromegatrol II on ebay for $250.00 ($1100.00 @ B&H), and all the heads work perfectly! I am really...

One of the heads worked, I'm not sure about the other one. I have the standard power supply. It looks old, the cord has "dry-rot". I bought it used on ebay several years ago, while I built and...

I have 2 used Chromega Dichroic II heads, and the main light in neither of the heads work. It is either the power source, lamp sockets, or something internal like circuit boards. Reason would tell me...

I have been using a Velbon Carmagne 640 carbon fiber with a matching Velbon PH-640B head. I like it just fine! I too use the Toyo 45A II. Primarily I use it on the rocky shorelines of the 30,000...
