    New fish in MF pond

    in Medium Format

    Posted

    220 format film is twice as long, has no backing paper, requires a different magazine, and is difficult to find. Some film magazines can be switched between the 2 formats.

     

    Zone focussing is guess based focussing based on approximate distance and depth of field. If you are at f/11 then at 2 metres from the lens you know that you have X metres of DOF so anybody between 2metres and 2+X metres is in sufficient focus.

     

    Hyperfocal focussing is like Zone focussing except that your DOF and exact focus point is adjusted to include infinity focus, so anything from a particular distance to the horizon should be in sufficient focus.

     

    I don't know your specific camera, but DOF for the larger formats is very small. Probably about '2 stops' less that you are accustomed to with your 35mm lenses.

     

    Good luck and experiment heaps ;-)

    Thanks,

    Cleaning Film Scanner Sensor (FS4000US)

    in The Digital Darkroom: Process, Technique & Printing

    A folloup to my previous response:

     

    The sticking I've solved using candle wax. In fact I've solved a number of sticking problems by rubbing candle wax onto surfaces. The top and bottom of the film holder are worth coating in wax, to stop the above mentioned skipping/shuddering problem. I'm still using this scanner after more than 4 years. I still need to periodically blow out the sensor assembly. Works wonderfully well.

     

    Now that the only new scanners you can buy are the rather expensive Nikon ones, this is more relevant than ever ;-)

    Cartoons and Street

    in Street & Documentary

    Posted

    <p>

    I've just watched 'American Splendor'. I noticed, felt a strong relationship

    between the way that cartoon stories are usually told and what happens in street

    pictures. Almost to the extent that it should be possible to construct cartoon

    strip narratives from street pictures just by arranging them and adding the

    'voice-over' or a caption.

    </p>

    <p>

    In the past I was struck by the similarity between Breugal's street-life

    pictures of various towns in the Netherlands and street photographs. Of course

    he crammed the (single) frame with the entire story, and you need to pore over

    the whole picture with a magnifying glass to see the crests over the doors of

    the houses in the background etc. The miniscule detail is quite important for

    example to work out what the celebration is about.

    </p>

    <p>

    In photographs we usually try to simplify complexity in composition, although I

    have never quite been aware why at an intellectual level. But at the same time

    details can be conveyed to the viewer in extraordinary quantity.

    </p><p>

    Anyway, I wondered to what extent others thought that way.

    Can you think of examples of cartoon-strip like street stories?

    To what extent do the old photo-journalism stories work like that?

    The most obvious example I can find at the moment...<br>

    Printing Street Shots

    in Street & Documentary

    Posted

    <p>I think you need to talk about specific examples, like Marc did above. Otherwise generalities lead nowhere. In this example (and indeed in the whole series of 100 or so shots) I just used photoshop levels, chose a dark point, chose a white point and then adjusted the middle slider to emphasise the main subject. Is that too much? I don't think so. Is it perfect? No way, I hate that 'thing' behind her neck. One day I may try to make a better scan and burn that area.
