<p>Thanks for the responses. Will let you know how it turns out. This was the first time using a circular filter on a TLR for me and it was tricky business.</p>

<p>This weekend I shot a Mamiya C330 with circular polarizer on the taking lens for the first time. I put the polarizer on the viewing lens first and then noted the positions at various points in relation to the sun, then transferred the filter to the taking lens to take most of the shots in the sun. I think I made a mistake on this filter, though, and compensated two full stops when metering. I'm wondering what to expect here and whether it's enough to even tell my lab (now that I look it up again today, this filter loses about a stop and a half). I was using Ektar, which has latitude anyway, so I'm thinking I'll just go ahead and develop at box speed and see what I come up with. Any thoughts? Thanks.</p>

<p>Just as an update - developed the test roll tonight. Used same formulas, same procedure, everything - and it came out perfect this time. I must have done something stupid last time, but can't figure out what it was. Anyway, I feel a little more comfortable that it probably isn't the camera now (hope not, that thing takes amazing photos). Thanks for all the guidance and suggestions in here. This is a really helpful group of folks in this forum.</p>

<p>Thanks all. Yeah, film was loaded correctly and the back was tight and screwed properly. I honestly have no idea what could have happened. I talked to the prior owner of the camera and he never had the issue. I really think this was a fluke, but I guess I will find out after the fresh roll in the camera now. I am going to have to re-shoot that little chapel. The exposure with black and white is beautiful to me, and I NEED to get the compositions I had on the lost roll. I worked hard on several of those shots for balance (the shot that came out was the first composition, which I don't care for), and ended up really liking the look of that pulled Ilford!</p>

<p>Yes, it does. It is currently set to the locked position. Feels like it's moving when I turn the lock button. Do you think it might be engaging itself mid-roll?</p>

<p>Here's the <a href=" surviving negative</a>, slightly worse for the wear. :)<br> I just tested the shutter - it's opening and closing just fine (beautifully even). I'm left to believe there was some sort of problem with the way the film was loaded, or a problem with that roll of film itself. I'm going to finish a fresh roll and see how this one does. Appreciate all the responses.</p>

<p>Alan Marcus, I think you might be onto something. The edge printing is OK and developed fine with the first image. The film went right onto the reel with ease (which surprised me), so I really think it was spooled correctly. I guess I'm going to have to look closer at the camera. Thanks for helping me narrow it down.</p>

<p>Thanks, Lex. This is a Mamiya C330, so everything is manual. I can feel the film advancing (there is tension on the roll as I wind), and it seemed to catch each frame correctly and knew when the roll was finished. I'm kind of stumped.</p>

<p>Thanks Andrew ... hmm, now I'm wondering. I would think at least something would have shown up in the other frames even if my dilution ratio was off. The camera worked great the first roll I shot with it. I metered incorrectly (shot 400 speed film at 100), but realized what I had done after five shots, so I continued metering the rest of the roll that way and then pulled the film. Shutter seems fine. Opening and snapping shut perfectly.</p>

<p>EDIT - I think I've already figured this out on my own. It would really help if I was a little stronger with basic MATH.<br> =====================<br> I posted a question a few weeks back about pulling 120 film. I had the film in the camera for quite a while before I finished the roll, so I finished it this week and developed tonight (I use the word "developed" lightly).<br /> I also bought a new batch of Rodinal to start working with. When I finished developing/fixing, only the first frame on the roll was exposed - the rest is just blank film. Trying to figure out where I went wrong in the process, as I'm assuming it's operator error. I'm pretty new at this, obviously.<br /> I mixed a 1:50 batch of Rodinal and pulled two stops (because I accidentally exposed 400 speed film at 100 settings). I used 20 oz of water, and .5 oz of developer (sorry, I have to use ounces for now because I need L/ml measuring tubes).<br /> Am I calculating ratios incorrectly? Is it possible this Rodinal is a bad batch? All the above? Scratching my head. I can't figure out why a single frame would develop correctly but nothing else. Saw a similar thread below, which was helpful, but wondered if you could point out what I'm screwing up. Thanks in advance for any help from those more experienced at this.<br /> ======================<br /><br /></p>

<p>Thanks for all the responses. I actually did a two stop push development on a roll last night that came out decent, but looking a bit underexposed. This is a trial-and-error process for me at this point, until I get a feel for the developer and the process. I just ordered some fresh Rodinal for this project, and I'm planning to do the next pushed roll by stand developing. I'm anxious to see how it comes out.<br> <br /> I still haven't worked on the pulled roll, as I have two shots left and it's medium format, so I'm being picky about what I use the film on. And I definitely want to use the Rodinal on it.<br> <br /> By the way - - I found a terrific darkroom app for my phone that automatically adjusts developer times depending on the circumstances. I love this thing. Works great.</p>

<p>Thanks for the help. I appreciate it.</p>

<p>I'll use Rodinal.</p>

<p>I request the lab to push film all the time, but today I screwed up and shot a roll of HP5 400 at 100 and I'm trying to get into processing at home. Anyone know of good recipes for pulling? It's weird how I can't seem to find any online, and mass dev chart only seems to cover pushing (?). If it's just a matter of cutting the processing time, how much would I cut for two stops? Thanks much.</p>
