Why? Why not just look at the GG and decide for yourself if it is in focus or not? I realize all these tools are helpful to some % of the market, and interesting math and programming programs in their own right.... But do you really NEED them? DO you NEED your Palm if you are in a beautiful place, alone, and peaceful? Get out and smell the roses.....That's my motto.... Frank Filippone red735i@xxxxxxxxxxxxx I have been playing with Bob Wheeler's VadeMecum (http://www.bobwheeler.com/photo/Software/software.html), which is a set of usefull programs for the (LF) photographer which runs oa on a Palm device. Anyway the program I like the most is called Tiltb, this program helps you to find the amount of tilt (in degrees or top movement) needed to get something in front of (A), and something at the back (B) higher up in focus.It is based (not novel) on measuring, by back focusing the difference between A and B on the rail, and the difference between A and B on the groundglass. Both distances and the distance from the camera to the tilted plane are fed into the TiltB program, which gives you the degree tilt or the amount of topmovement of the front standard. Since I use mainly an old Linhof Technika III in the field, I cannot use back focus (it hasn't), but I assume I can use front focus for that, right? A more difficult part is how to measure the amount of top movement. A Tech III has no front tilt, only back tilt. A way around this is to do back tilt, and drop the bed (making front and back parralel again, and a front raise. So now the back tilt is turned into a front tilt. I now measure the amount of top movement by measuring from the back panel (actually box), somehow I have the feeling that this is not entirely correct. OTOH I did some testing of this procedure in my living room, and the resulting tilted plane nicely brought the desired subjects in focus, have to print the negatives yet though, Best, Cor ====================================To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there. ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
