hi h2o
Actually I have another msg but was cut-off halfway due to CS database pblm.
I shoot in manual mode on my F90X. I set Shutter sp to 1/100secs, Aperture from f16-f32.
Strobes to TTL & less than 30cm from subject & slides velvia or proviaF.
Strobes angle, is almost perpendicular but slight in front of subject and at a lower angle of 20-30degs. The reason I tried this is that I want the background to be black. Occasionally I use a close-up 4T on my 105mm macro. with this fitted I can have a "electronic" aperture of f45 & f64, but u will need the strobes to be much closer - approx 20cm from subject.
U can also use another YS30 set to slave mode (no connection to camera). Ask the DM to hold to any position that u want (perhaps from bottom up angle) + two YS120 at standard position. if u do not have a 3rd "mini" strobe, try detaching one YS120 and ask DM to hold for u in position. This will ensure at least one strobe hit the subject correctly.
End of the day, give the DM a tip !!!
The rest is up to u yr composition & how u want all of us to view the images thru yr eyes.
Happy shooting !!! cheers
