Lets clarify a few things

early in the thread she said she was using strobe with a 210m lens. So

you can not compensate with shutter speeds

giving a formula with a 6" lens as an example may not be helpful.


I would still suggest using the general rule of thumb I posted earlier as it applies to all focal lengths (yes, even telephoto lenses) and all films.

Yes, Steve, we don't want to complicate things - might send me right 'round the bend! LOL Really enjoying your book, by the way.

Thanks everyone for the help so far :smile:

another to remember way to do it - - think of your focal lenght as an fstop, so you are using a 8 1/4 " lens ( think f 8 + a little bit ) then at 11 ( + a little bit) " it will be one fstop more you have to open up, ( or one shutter speed more to compensate ) then at 16" ( + ...) you would open up 2 fstops, 22 " ( + ... ) it would be 3 and so on ... since you are using a leaf shutter you can compensate mostly by shutter speeds, so can stop down more and not worry about depth of field.

Is anybody else getting a throbbing headache? Run with Steve's plan!

I keep an actual wooden ruler in my camera bag that has the bellows extension compensations marked right on it (in 1/2 stop increments) for each of my lenses. All I do is hold one end at the lensboard and see what compensation is needed (for that lens) by seeing which compensation number is closest to the film plane.

The less I have to fumble over numbers while being creative, the better!

Murray

(Added later) Start your measurement from the "nodal point" of the lens...(the point at which the image inverts within the lens)...so if you've used swings or tilts, measure from where the lens meets the lensboard. Same goes for the film plane...(measure for the middle). That'll get you in the ballpark.
