Resizing a JPEG pic

Posted By Ron Streetenberger

Start using "Picassa". It's free and does exactly what you want regarding resizing.

1000MM f10 Russian reflex camera lens

Posted By Ron Streetenberger

I was told that the lens was the military variety by the seller. I figured that was the case as it lacked the usual "made in the USSR/Russia" marking. It does however show the LOMO icon.

CAVE: Bristol 447 clock drive motor

Any clock makes two "hour hand rotations" in 24 hours. Any set of gears with a 2:1 ratio will work. the greater number of teeth in each gear, the greater the accuracy. 10:20 is good. 50:100 better, etc. I once made a barn door rig which worked perfectly for exposures less than 1 hour.
