  1. Thanks everyone, I appreciate the feedback. I cleaned the prism and all of my lenses as best as I could. Hopefully my next batch of film comes out fine now.
  2. I double checked, and no I don't think its from the scan. The reason is that the same spots appear in the same location on some B&W film that was scanned on a different scanner altogether.
  3. For some reason my image doesn’t appear to be embedding in my posts. Hopefully it shows up below:
  4. Sure thing Mark, unfortunately I have to squash the file down to JPEG. Here you are: Without circles
  5. Hey Mark, Sorry, I should have included a frame. I've attacked a Tiff below...I darkened the image with a cruddy grade to show what i'm talking about. They are faint and very soft. As i said before, its only in this particular shot because I was closed down, but it was also in a previous reel as well. I have since cleaned off my prism, although I didnt see anything out of the ordinary. This is probably a farfetched question, but there's no way debris could get etched into the prism glass, right? Also, just a note...I shoot a lot of expired stock....I'm wondering if it might have been flakes of emulsion that chipped off and flew onto the prism while the camera was running?
  6. Thanks Dom, I appreciate the information. I checked my prism again tonight and didn’t see anything out of the ordinary, but gave it a cleanings anyways. I inspected all of my lenses with a lighted loupe and all of them have some form of debris inside, but I have never had this issue with my lenses stopped down to f/22 before. the only thing I could think of that may have caused it was that I shot a music video in a warehouse a few months back, maybe dust or something got into the film chamber when I changed reels (I did not have a dark bag) and kicked up behind the prism or perhaps it got on the prism when using the turret to swap lenses. I did notice it a bit on that footage when shooting a bright sky, and noticed the same on my recent footage shooting a similar scene. The spots are in the same exact place on both batches. assuming it is the prism, I suppose I should give it a quick look each time I load.
  7. Thanks Bruce, do you have any tips on how to clean the bolex prism without damaging it? I checked it out and it seemed to be clean, but I could have missed something. also, the specs inside of my Switar don’t appear to be dust, it definitely looks like a liquid of some sort.
  8. Hey everyone, I recently got some scans back and they look great, but on one shot in particular I noticed an issue with dark circles all throughout the images. I was wondering if this is a lens issue or an issue with my bolex prism? The lens was stopped down to f/22 and I also closed the shutter down an extra stop since these were shots of a bright sky. I have also noticed this issue on previous scans. I did notice in my one Switar lens that there are a bunch of little droplets of what appear to be grease or liquid, could this cause such an issue? The spots are soft, almost identical to sensor dust spots on a digital camera, but they are much larger in diameter. Thank you in advance. -Derick

  11. Hey everyone, I wanted to see if anyone had any tips on shooting ESTAR based film in a bolex (or similar) camera? From my understanding, polyester film is long pitched as far as perforations go and it is also a very strong base. I know some of you would not recommend using it in camera, but I have seen it done. I wanted to ask if there was a specific way I should load the camera or if I could simply autoload as normal? I ask because i've been told that if the camera jams, polyester film could potentially break my camera which would mean repairs 😥. Also, whats a good recommended ASA to rate both 3383 & 3378? Thanks in advance!
  12. Hey everyone, I havent posted in some time, but I wanted to ask a few questions about incident readings. Up until now i've been using light meter apps for my Iphone in reflected mode with pretty decent results, but I was recently given a Sekonic incident meter. I'd love to use this because from my understanding, incident readings are more precise, but the main thing is that I mostly shoot street/docu & landscapes. How would I go about taking an incident reading if I cant get close to my subject? Also, when compared to the readings my reflected meter (phone app) gives me, my incident readings seem very "overexposed"....By like 2 sometimes 3 stops over, Is this normal? I've compared the sekonic with other handheld meters and it seems to match. Thanks in advance!
  13. Hey, sorry everyone this camera has been sold. I am selling an Angeniuex 12-120 type C for Bolex Rx though if anyone is interested.
