I took off the UV filter and I bought the lens hood. The problem is still there.

I noticed there is a problem with some of the pictures taken with Mamiya RB67 + 65mm f4.5 lens. You can see a brighter spot of light almost in the middle of the image (it almost looks like a smoke). This happens only in situations when the subject is quite dark but the background is very bright (please see attached photographs). I went to the camera repair shop. They said it's not caused by a light leak. It's usually the problem with the lens (some mold) but they checked it and it had no problems. I've read that when using UV filters (mine is not very expensive) there can be some flares occuring on the images. Could that be the problem? Has anyone ever experienced something similar? Could you kindly help me to solve this issue? Thank you very much!

<p>you are right, Craig. it is not the problem of the weather conditions...</p>

<p>Craig: have you ever been shooting during typhoon in the tropical climate?</p>

<p>reply from Kodak:<br> <br />'Based on your images, we believe this film may have experienced some abnormal shipping / storage conditions after it left the factory and our warehouse.</p> <p >In particular, the attached image looks like the backing paper was stuck to the emulsion.</p> <p >In January of this year we implemented some changes to make our backing paper more robust in the face of less than ideal shipping or storage conditions. We believe that this should substantially reduce the potential for this type of problem going forward.<br> PORTRA 160 produced with this new paper starts with emulsion <strong>6132</strong>. '</p>

<p>if I were 100% sure that the problem is the seller, I wouldn't have asked this question. as I wrote, he is the main kodak distributor for the whole country and I've been buying films from him for years. never had problems before. only this year. also I don't think I could buy kodak portra 160 in the country where I am planning to go (at least at the reasonable price, also not very reliable). I want to make sure it's not the camera, weather, lab, kodak or anything else before I go. I thought someone here might have had similar problem before and could help me.</p>

<p>I bought kodak portra 160 (120) from the main kodak distributor in Taiwan. I've been buying films from him for years and I've never had problems before. I took some pictures for my project in July. I developed them in Jazz Image in Taipei (pro lab) and scanned with my Epson v700. I noticed that on most of the pictures there are visible 'kodak' words and film numbers. At first I thought that it is because of my camera, that it got wet inside (I use Mamiya 6) and it made the films moist. I went to camera repair shop to make sure all is good. The guy told me that this type of signs are the result of hot weather on film. I used the films two days after buying them and I don't think they were affected by hot weather in the meantime or after shooting. I asked the film seller about the possible reason and he said that sometimes different film batches might have some problems. The expiry date of those films was 01/2017 so I thought - maybe it was the problem of the films. But then I bought more films from him, scanned recently and I have the same problem (expiry date is 06/2017). When I asked him, how he stores his films, he said, he keeps them inside the fridge but they were never cold when I bought them. What do you think might be the reason for this problem? Could it be my camera (film gets wet), bad developing (Jazz Image's fault), bad storing by seller (too hot in the summer), problems with kodak portra 160 or something else? I am about to go for a trip and need to order 100 films. I need to make sure there are no problems this time. Also I am very unhappy about this issue. Please see the examples. One film was very bad, the rest is not so obvious (need to enlarge the picture to see it).<br /><br> <a href="https://goo.gl/photos/vKdoQ6jTHvJsKyaQ6">https://goo.gl/photos/vKdoQ6jTHvJsKyaQ6</a></p><div></div>

<p>continued from this post: http://www.photo.net/medium-format-photography-forum/00WDH3<br> so I finally went to Iceland in the winter time with my dad's two Pentacons - Six and Six TL with two 80mm lenses, one 50mm and one tele lens (200mm or 250mm - I don't remember). I am quite satisfied with the results ( ). there were few things I liked and few I didn't about these cameras, here are my comments:<br> - it turned out that some of my photographs taken with 1/30 shutter speed were not very sharp (I might have used 1/15 few times as well)<br> - Pentacons don't have build in light meter so I had to buy an external one so no quick shots (focusing is not fast as well)<br> - I like to get my perspective straight so waist-level finder focusing was difficult in situations when I wanted my camera as high as possible<br> - one of the cameras stopped working properly due to heavy snow/low temperatures and the other had some issues with lens. that was one of the reasons that I had to shorten my trip (the other reasons might have been: I got sick, had two car rollovers and no money left)<br> - Pentacon Six is just too heavy, together with my Manfrotto tripod from the stone age it was hell to hike in the mountains with all that snow, ice, wind and cold<br> - I used 80mm lens 95% of the time so didn't really need to take the huge and heavy 50mm (not even mentioning the tele lens)<br> - I like 6x6 format but there were many times when it felt there is too much space to fill at the bottom and top and I felt it's too short on the sides<br> - it felt magical to use these cameras: the sound, the beautiful square image (dissapearing whenever I pressed the button)</p> <p>I sold both of my father's Pentacons (after making sure they work properly again). After that I tried Koni Omega (too heavy), Shen Hao large format (too heavy and it takes ages to take a photograph, on the other hand the results are amazing and it kind of slows you down, it's like meditation), fuji gw690II (too big, rangefinder). I don't know why but I bought Mamiya 6 even knowing that rangefinders just don't work for me (I love precise composition and straight horizons too much). I like that Mamiya 6 is so small and light though, also quick focusing + light meter. Now I'm planning two trips, one would include lots of sand and heat, the other tropical climate. I want to finally choose the right camera for my travels. Here are few things I care about...</p> <p><em>important:</em><br> - the camera should <strong>not</strong> be <strong>very big and heavy</strong><br> - I need to be able to take sharp photographs using <strong>1/30</strong> shutter speed <strong>handheld</strong><br> - <strong>sharp</strong>, high quality <strong>lens</strong> (ideally f2.8 or faster)<br> - I'm into <strong>precise composition</strong> - what I see is what I want to get so <strong>no</strong> more <strong>rangefinders</strong> for me thank you very much (not sure about TLRs, never used one)<br> - I'm planning to sell <strong>large</strong>, high quality<strong> prints</strong> (min 24"x30")<br> - the camera has to be <strong>reliable</strong> and work properly in <strong>extreme conditions</strong><br> <strong> </strong><br> <em>less important but still:</em><br> - <strong>built-in light meter </strong>but not too electronic (I like the feel of mechanics and magic of film, otherwise I would go for Canon 5D II)<br> - although I'm quite adjustable with format I prefer something <strong>slightly rectangular</strong> like 6x7, 4x5 or 6x4.5 (6x9 is probably too long), after said that I could work with 6x6 as well<br> - 80% of my photographs are in <strong>landscape format</strong> (not sure about 6x4.5 then)<br> - when I take portraits I like to use shallow depth of field (f2.8-f4) so would be great if camera was able to shoot <strong>faster than 1/500s</strong> (incase it's sunny)<br> - would be great if you could use the camera in a <strong>'</strong><strong>periscope'</strong> position (handheld of course) or at least on the eye level<br> - I know usually you have to spend more if you want more but <strong>price does matter</strong> as well, although I would prefer to safe for a bit longer rather than get something I'm not happy with</p> <p>so I guess my choice is between 6x4.5 format cameras (not sure if large prints are ok, problems with landscape format shooting?), TLRs (not sure about precise composition) and Hasselblad or Rollei (both not cheap, I don't think you can handhold them at 1/30). </p> <p> </p>
