Peter, my drum times are about the same. I was hoping someone had used this combination with BTZS.

"e-mail Fred at the View Camera Store and ask him--he's going to be doing the tests." Better than that: I spoke to him on the phone this afternoon. Hence, my post here. "My experience with Pyrocat would be that your development time should be closer to 12-15 minutes. I'm not sure where you got the 4 min time from. It's amazing that you got any density at all." I got the 4 min time from Fred. He uses this time to determine if the dilution is correct. My times with Pyrocat are much like yours except when using constant agitation. FWIW, BTZS is or was used successfully by Sandy King.

Hi Larry, I'm using 60ml of developer per 4x5 sheet. Fred told me that it seems to be taking a long time for the 1:1:100 dilution to begin working (of course I have no idea how he knows this). What's puzzling me is that Sandy King uses these params and says that he gets excellent results. I did note, and to your point, that Sandy calls for 75ml per sheet. Would 15ml of working solution make that big of a difference? http://www.pyrocat-hd.com/html/times.html

I asked on APUG but seem to be getting nowhere... I need some assistance and I am hoping someone with real-world experience might chime in. I am trying to use Pyrocat-HD (1:1:100) @ 21° in BTZS tubes to develop FP4+. I am having tests done by The View Camera Store and the initial test for dilution is to develop for 4 minutes. The problem is that the step wedge is too thin at 4 minutes using the above parameters. I barely have any density at step 11. * If I am getting an exceptionally thin neg at 4 minutes, does it point to an error on my part or a characteristic of Pyrocat-HD? * What is the best dilution and/or temp to use Pyrocat-HD with FP4+ in BTZS tubes? Thank you, Jim

<p>Allan, the view of the Great Falls is amazing! As a (former) whitewater kayaker I've seen so many views of them but never like this.</p> <p>This has to be the richest month of w/nw. Every shot is a stand-out!</p>

<p>Great photos!</p>

<blockquote> <p>Jim Trahan. I think your post is kind of strange. On the one hand you say a 12" "limit" is "laughable", yet say also that there's much left on the negative, which is exactly what I'd expect from a scanner with clear limitations in resolution and Dmax.</p> </blockquote> <p>To be clear I am only speaking about B&W because I don't wet print color...</p> <p>Even comparing Nikon B&W scans to a wet print of the same negative, there's a lot more in the wet print. I haven't seen a digital sensor surpass what I can get from a good wet print. Nevertheless, It's exactly what I would expect from a digital sensor. It's not a large format contact print but it's more than adequate for sharing online or printing under 20". </p>

<blockquote> <p>I have and use a V700 and there is no shortage of nay sayers that will insist I can't do what I obviously can do. Like the review that got dropped, one has to consider the source. Skill is involved and without it, garbage scans will ensue.</p> </blockquote> <p>I agree. The restriction of 12" is laughable to. I get great results with the v750 compared to other scans I've seen.</p> <p>However, there's much left on the negative. This is especially noticeable when scanning 4x5s: printable highlights get blown out, fine detail seen under a 6x loup renders as a mere suggestion of detail in a scan.</p> <p>I suspect to get the most from a negative, and I've seen this with my own eyes, is to wet print with high quality optics. Tonality is much better, even in high contrast prints, compared to a scan of the same negative.</p>

<p>I hope everyone's having a good start to the new year. We had great participation and some very fine photos last week. It's sharing time!</p> <p><em>Mamiya 7ii / 80mm / FP4+ / Pyrocat</em><br> Please click <strong><a href=" to view larger on Flickr.</p> <div></div>

<p>Hindsight being 20/20, I wish they had gone with a non-proprietary connector but Firewire made sense at the time. Another with: I wish they made Firewire to USB converters (that actually work).</p>

<p>I concur with Ray. When I compare the Nikon CoolScan IV to the Epson 750, pixel to pixel, the 15 y/o Nikon edges it out. If you only shoot 135, the CoolScan IV is a great choice. I only use the Epson for 120 and 4x5. </p> <p>Ray, is the 9000 firewire only?</p>

<p>I like that shot, Knut. It has a creepy vibe yet feels familiar.</p> <p>Lovely work, Eddie.</p>

<blockquote> <p>Don`t put 6x6 cameras away... some square format cameras have all the advantages of a 6x7 (some even more) on a considerable smaller package...</p> </blockquote> <p>I love my 6x7s but even the Mamiya 7ii is larger than I want to carry every day. I can fit 2 TLRs into the same small rangefinder bag I use for my 35mm rangefinder. It's hard to beat a TLR when it comes to size of the camera and format. Yeah, some people don't get on with them and I resisted using them for years, but I have found TLRs to be practical and the 6x6 format liberating. </p>

<p>Condolences, E. She looks like she was a strong and beautiful person, a gift to have known. </p>

<p>Congratulations! The recognition is well deserved, Charlie.</p>

<p>Whispers and secrets?</p>

<p>Michael, I think we are fortunate to live so close to neat places. I'm getting bored with the landscape here. I've become so accustomed to it I can no longer see it with new eyes.</p> <p>Skeeter, excellent. That's in the same spirit. I love things like that.</p>

<p>Simply outstanding work, Charlie. I'm bowled over. </p>

<p>I spent Thanksgiving on the coastal plains of Texas this year and found this on the edge of town. This was a deeply gray day and I caught this between showers. I took my time setting up but as soon as I tripped the shutter it began to pour.</p> <p><em>Chamonix 045F1 / 90mm Grandagon-N / Yellow Filter / FP4+ / Pyrocat-HD</em><br> <em> </em><br> Please click <a href=" to view larger on Flickr.</p> <p> </p><div></div>

<p>Thank you for the encouragement to post, gentlemen. I've switched to rotary processing my B&W and have spent most of my free time trying to find the EI and development times of my films. I've also started learning 4x5, which has been a blast but I have a very slow output. I'm spoiled by all the movements on large format cameras. In time I hope to be able to capture the same kinds of scenes I am able to get with 35mm and medium format.</p> <p><em>Chamonix 045F1 / 150mm Sironar-N / Provia 100F</em></p> <p>Please click <strong><a href=" to view larger on Flickr.
