Hi All, I just purchased a used Super Ikonta 531/16. The camera was purchased cheap from someone who never used it, and it was given to him by his neighbor. All the mechanics seem to be operating, but the only problem is that I cannot engage the shutter. ie. the shutter will not close for me to release it. I tried to find a way to cock it, either by pushing down (clockwise), or up (counter clockwise). It does not hold shut. There is already film in it as I didn't realize I had this problem until I loaded the camera, The film will not advance because it is set up not to allow double exposures. Does anyone have any tips / advice? I can send photos if needed. While I do plan on getting a CLA on the camera, I wanted to test it to see if it could yield an image. the other rings/ mechanics work. I can turn all the dials. The other question I had was with the range finder. When I look at the little square inside and turn the focus ring, it does not go 'out' / create shifting lines. Any advice would be helpful. Thanks so much! Sincerely Lili

Yes, This much I understand. However, what I am confused about - because it is infrared, is -- when the roll comes out clear - does this mean the film was overexposed or underexposed? When it comes out black, does it mean it was not exposed or it was overexposed? Am I looking at a positive reversal roll after processing and development, or am I looking at a negative? Both make a huge difference in terms of how to read the whites(clear) and blacks. thanks so much, lili

Hi All, I got my film back from the lab - the test roll. I shot a few images without the filter at apx 4 sec bulb (holga shutter), a few shots with an orange filter and a few shots with the infrared IR 720 opaque filter. The strange results yield this - i get a faint image with the orange filter, but it's mostly clear with speckles of black. (from the sky surrounding tree folliage)... Most of the roll was clear! My question is this - I am getting very confused. If the roll of this Konica is clear, does this mean that I did not expose the film for long enough (4 seconds / some shots were double exposed and were still clear)... Or... That the images were exposed for too long! I got a very faint 'something' with an orange filter... this film is super expired (yes, I know I shouldn't but I do, the film is from 2000 but has been sitting in the fridge). I know the camera works with Black and White and Ektrachrome because the lab processed that... OR do you think their developing times on the infrared were set for too long. I still have 2 rolls of infrared I have not processed and shot in Wyoming, and I am fearful if I do, it will be clear again . Furthermore, I would still like to continue to shoot infrared because I have this unsused film, and would prefer not to toss it. I just need to figure out if I should be giving 15 second exposures on a clear or cloudy day.... instead of 4 second exposures Thanks so much Lili

Dear All, Thank you for all the advice. I went out and shot a roll of this film with an orange filter and without a filter and also with the infrared IR 720 filter. Based on the specs of the Konica film, I am beginning to suspect that the film cannot handle the IR 720 filter - it is far too opaque and if the film speed has an average asa 72, then - with the opaque black IR 720 filter, It's highly possible there would be no exposure. The last rolls that yielded images from a few years ago were when I shot with a red filter, not a specifically IR 720 filter. I'll keep you posted when I get the test roll back from the lab! - I just am interested to know what is the difference between using a cheap red filter on konica IR film vs using an IR 720 filter ? Thanks, Lili

Thanks, sorry for this! best, lili

Thanks for all the response. So, is there any chance a cheap IR720 filter from Hong Kong (16usd vs 77usd for the hoya) could have been so opaque that no image would be visible / there would be a clear negative?)... Or is it more likely that the lab developed the infrared film incorrectly using a black and white dip and dunk method that was not appropriate to infrared film? best Lili

Dear All, Hi, I have a question about Infrared film. I was out in Wyoming filming with my Holga camera. I shot 4 rolls of 120mm film - Expired Infrared 750nm that I had stored in my fridge for several years. I shot on my plastic holga on Bulb setting with an approximate of 1 second in bright bright daylight in the open plains of wyoming. I used a 46mm IR NM filter that looks opaque black unless you point it to bright light. There was one roll that where I opened the back chamber to check and see if I had advanced the film properly (I sealed up the back of the camera to prevent light leaks so I could only guess whether I was on the right frame by advancing the frame 34 clicks). I placed the film back in an aluminum wrapper, but did not put it in a black bag. I made sure that when flying back to NYC that the film did not go through the x ray machine. *I read somewhere that 750 nm is actually not that senstive and will not fog if you do not put it in a black bag... So I brought my film to a lab that processes black and white film. The lab has a dip and dunk machine and I explicitly said they must turn off any lights that emit infrared light. They said okay. The rolls (I only have 2 / 4 processed so far) came back completely transparent, except for 1 roll that had a dark frame that seemed to suggest the moment when I opened the back chamber to see if the roll was finished. I cannot imagine that the roll was not exposed at all... or 2 rolls were completely fogged to be transparent. *Sorry I am a bit confused as to whether the film roll of 120mm 750 konica nm infrared is negative or positive. I am inclined to believe that it is positive, which means if the film was exposed, the roll would turn black. The clear rolls have the frame number and the edge dma8 (is that what you call it)? Which the lab claims is proof that they processed the film okay. So... It's all a bit of mystery to me - either -- the infrared filter was so dark that I should have had the holga camera set to bulb and exposed for more than 1 second in bright daylight ... or the lab did something wrong with processing (which means I might have a chance at saving the images if I sent it to another lab)... or the film got fogged when in transport traveling from wyoming to nyc. Still, why would 2 rolls not yield any images at all? I could have sworn my film was exposed in the bright sun of wyoming! thanks so much Lili
