No difference in photog w/ long lenses.

I'll try the V- trick...sounds interesting. (Except I have very short arms.)I've usually tried to grab a pole with my left hand, bend the elbow, create a notch for the lens...shoot. But there's not always a pole around.

I've heard of using a cut to length dog leash, leather...tipod screw on 1 end...foot thru loop on the other...pull up against the leash screwed into tripod hole...variation on an earlier post.

Other tricks I've tried w/Pro1...shorten neckstrap...turn LCD horizontal...pull down on neckstrap w/both hands gripping camera...lean back against solid object...feet spread...frame on LCD...tends to reduce tremors...have shot down to 1/8th with acceptable results...not a choice on 20D...unless you're just making a wide shot to straighten later.

My usual slow speed shot is both elbows tucked tightly into body...slowly depress shutter to the extent that you don't know exactly when it will fire.
Also agree that 3 shots are better than 1. On 35mms used to lay finger across shutter release and flex finger to depress shutter...not push it.

Self-timer idea is great for ceilings, etc. People watching think you are nuts, tho...gets interesting interplay. Have even had security keep others back...

Good thread.
