    Projecting Medium Format

    "If you switch from a P11 to a newer Rollei MF Projector You don't need to dismount and remount each slide, is sufficient to changhe (reverse) its positione on the tray."

     

    The glass on one side (light source side) is slightly pearled. If reversed, there will be a loss of sharpness. Plastic mount (one side dark, other side white) will be reversed also.

    "If you gotta use lens caps, paint 'em fluorescent orange!"

     

    Or like the pitot cover on the aircraft where on a long strip it is written "Caution, Remove before flight", you can glue a long strip on your lens cover with the mention "Remove before each photo".

    "There were all kinds of horror stories of pictures lost that way. Therefore I never used lens caps and still don't."

     

    If shooting at people, they probably will inform you of your mistake, but you can lost pictures in a more technically way: by forgeting to remove an infrared filter! You can also forgot a 80A, 85, ND, softar or any other filter. So what, never use filters also? You can even have the wrong lens mounted, for example, viewing through a 21mm finder while a telephoto is mounted on the body. So the best solution perhaps is to remove the lens and all accessories after each shoot and do a complete checklist before each new shoot. Perhaps the best solution to not waste film is to avoid to put one in the camera. (just kiddding)

    Yet I have to confess it, when I was young, I played with fire... as follow: Just for fun, I tried to shoot at the sun, at maximum aperture (F/2) and shutter speed to "B" for about 5 seconds. I got a hole in the film. But nothing for the curtains. I now know that because it was a SLR, the mirror protected them. Please don't try to do this with a M6 fitted with a F/1.0 noctilux! I was not aware of the risks that the camera can burn! There are no mention "Danger, risk of fire" in the camera user guide. Perhaps camera should be sold with a fire extinghinsher.

    Also there is a difference between the P11 projector and the new Rollei 6x6 projectors: The P11 projector takes the 6x6 slide tray on the LEFT, (because it takes the 35mm slides tray on the right) and the new projector takes 6x6 slide tray on the RIGHT. If you have slides mounted for the P11 and want to project them with a new projector, you will have to reverse them all for viewing them on the new projector. If they are between glasses, (as usually is the case) you will have to dismount and remount them all one by one as glasses on the lens side are clear and glasses on the light side are slightly translucide for better light distribution. The plastic border also is one side dark to minimise lens glaw and one side white to reflect and gain light. (that's for GEPE mounting).

    Future availability of 4x5 sheet film?

    in Large Format

    Posted

    Welcome to large format. I started photography with a 35mm SLR, then bought a Mamiya C330, then a Hasselblad, and now own also a Sinar F2. It is large format that I enjoy. I think there will be lot of 4x5 sheet films available even in 30 years. Digital may kill 35mm, but not LF, even if some sheets are discontinued. I think no many people can afford a US$12,000? phase one 144 MP digital back that will be obsolete later when always more performant and cheaper products appear on the market, except big advertisment companies. It is like computer, that have to be replaced every 3 to 5 years. Stock film, I still have outdated feb. 1997 B&W film in the freezer and they are still good.

    6x6 for RB67 Pro-S?

    in Medium Format

    Posted

    A 120 film gives you 10 6x7 or 12 6x6 slides. That is two more slides for 6x6. If the average price of a film is 5 dollars and you shoot 6x7 and cut the slides into 6x6 you will lose 1 dollar for the two missing slides per film . Considering the price of a new 6x6 back, it will be necessary to shoot hundreds of film to recover the amount paid for the 6x6 back. It is not worth it. And while cutting 6x7 into 6x6, it is also possible to correct framing.

    Konica IR

    in Black & White Practice

    <If you don't want to get IR glowing foliage, or any IR effects, then you should use a deep blue #47 wratten filter. That should completly obliterate any IR response from the film....>

     

    Blue filters and even green filters transmit IR. As the 47 cut of most of visible light, the IR effects (tree glowing) will be strong. The IR curve from Wratten 58, 61 is comparable to the curve of Wratten 88A and the IR curve of Wratten 47 is comparable to that of Wratten 87! You can have an excellent IR passing filter buy adding a deep red filter (29) with a 58 or 61 green.

    I shoot Konica with a HOYA R72 or Schott RG9 (for maximun IR effect) at 8-12 asa and have excellent results.

    As this film is not sensitive to green light, sensitivity and mild IR effect will be the same with any dark yellow, orange or normal red filters (Wratten equivalent to #12,15,16,21,22,23,24,25,26 and 29). After that, the IR effect will increase and sensitivity decrease with darker red filter like RG640, RG660, Wratten #70, RG695, Wratten #89B, RG715, Hoya R72, RG9, Wratten #88A, Hoya IR 76, RG780, Wratten #87.

    Looking for color infrared in 120 film

    in The Wet Darkroom: Film, Paper & Chemistry

    Posted

    100 feets (30.48 meters) of 70mm film gives about 38 rolls of 120 film (if one film is 80cm long). The expiry day of color IR film is short, so if there is only a few sold, the remaining of the film will soon be wasted (before the next summer). I think this is the reason why this service is no longer offered. Perhaps an order of more than 30 rolls, or all 38 rolls, will still be possible but in this case it may be less expensive and preferable to use 70mm film in 70mm back.

    Digital vs Film Weddings

    in Wedding & Event

    Posted

    In the past, about 25 years ago, I remember that I saw wedding photographer only use medium format cameras, 6x6 or 6x7. Then some years later, I saw photographer use 24x36mm SLR, and I remember being very disapointed! Now they use digital photography! We will soon see them using $9.99 single use plastic camera toys! I have been invited in weddings where I have seen "paid professional photographers using Nikon SLRs when the familly or guests are shooting with Hasselblad or Leica!

    I will always consider digital cameras as low resolution toys, as long as digital cameras are of some Megapixels. When we will be speaking of HUNDRED of Megapixels or GIGApixels, then perhaps I will consider them as cameras! If I compare film of 150 pairs of lines/mm resolution , that is 300 lines/mm, or 300 pixels/mm, so a 6x6 (56mmx56mm) negative or slide will be equivalent to 16800 x 16800 = 282.24 Megapixels. If I compare Kodachrome 64 or Velvia 50, we are well into GIGApixels. For now, with 8 Megapixels, we have the quality of a 16mm frame, so why not shoot with a 16mm Minox?
