Slit-scan

[Laci]

Hi all,

 

I’ve a 6x9 folding camera and I’m about to immerse myself in slit-scan. I’m wondering when I start winding the film which dot indicates the edge of the first frame because if it shows the number 1, I already wasted half of the first frame and at the end the last half of the 8th frame. 

I also have another question: I’ve read that if the winding knob is on the right of the camera then I should pan from right to left otherwise the slits will be in reverse order. Is that correct?

 

Thanks!

I think that the reason that there is a significant amount of unused film at each end is to give some margin for:

1. Variation of where the film is actually attached to the backing paper, I've not actually check how much variation there is and there's probably less now than there was when the standard was layed down.
2.  Differences between cameras, particularly those with mechanically-controlled advance (rather than using the red window).

I've not done any measurements but I don't think there's enough margin to get 9 6x9 frames, 17 6x4.5 is possible as I discovered when I mistook the "-" at the attachment region for a  "1" while using a Super- Ikonta in 645 mode, the second of the two extra frames was on the film the  first wasn't.

I'm not quite sure what you are planning, something like the overlapping panoramas that J.M. Golding often does with 127 cameras?

I think the direction is the other way, i.e take the left end of the scene first, then move to the right. Remember the image on  the film is inverted, so the right edge of the scene is at the left edge of the film, which will then move to the right edge of the next frame on the film.

Thank you James for your response! Basically I just wanna get into slit-scan panoramas and other stuffs experimenting with the technique but without losing parts of the frame. I’ll see, have some ideas in my mind and I’ll work on them.

Yea, that was my thought also that the direction is from the left to the right as the scene is upside down but thanks to strengthen my thoughs!

I really appreciate reccommending me J.M Golding as he’s awesome!!

I also got to 127film.blogspot.com through him and it’s a very useful site.

Thanks indeed all your help!
