potential replacement for Polaroid type 55 pos/neg film

Polaroid 545 holder

You will need one of these film holders to use the proposed new pos/neg instant film

If you own a 5×4″ camera and Polaroid 545 back you will be interested to hear about a project to develop a replacement for the much-lamented black & white positive+negative film, type 55.

Bob Crowley in the USA is working on this and has a Kickstarter project to raise some capital. Do consider helping him out: https://www.kickstarter.com/projects/bobcrowley/new55-film


Better flash for iPhone 5/5s

Here’s neat idea for iPhone 5/5s photographers: a better flash! It also functions as a video light and an off-camera modelling light – sounds great. Check out Kickstarter project Lightstrap at http://kck.st/1cWQ0ML or their video: 

I’ve ordered mine! If you’re new to Kickstarter make sure you are comfortable with the risks before you commit your hard-won cash.

120 film in Hasselblad 220 magazine

There is a steady trickle of well-used but serviceable Hasselblad V-series camera   components coming on the market at sometimes bargain prices (well, by Hasselblad standards, anyway).  This is great if, like me, you like to use black & white film occasionally.

220 film backs are particularly good value compared with the 120  magazines. Of course, the trouble is that no B&W film maker produces 220-size rolls any more.

Many people don’t realise that it is possible to use 220 backs with 120 film; the film registers in the same film plane no matter what film you use and the difference in pressure from the pressure plate seems to have no practical effect on film flatness or transport.  The frame spacing is different, each frame having more space between it and the next frame in the 220 back. It isn’t a huge difference but you can lose the 12th frame if you don’t compensate. Here’s how: when loading the film, stop when the arrow is as shown in the photo:

loading 120 film in 220 back

Miss-align the arrows as shown when loading 120 film into a 220 Hasselblad back (this probably applies to other makes of film back too)

The 220 film magazine will wind beyond the 12th frame so with 120 film you will be exposing on the the protective paper – oops! You just need to watch the frame counter – when you have exposed the 12th frame, cock the camera to frame 13 then wind on the film fully using the winder on the film back.

Voila – there’s still life in those 220 film backs!
