Question about SB800

Discussion in 'General Discussion' started by Bob the Spiderman, Apr 20, 2005.

  1. As some of you will know, last year I started a project on insects in flight using high ISO's and natural light with a D70 and either a Tamron 90mm Macro Di or a 70-300mmED. I have now bought a D2H plus a SB800, and want to use the SB800 off camera on a Manfotto flash bracket with a SC28; as a possible fill in flash and/or to reduce the ISO and speed factor needed to stop the insect in flight. Well, having never ever used a speedlight before, the SB800 manual may as well be written in Double Dutch for all the sense it makes to me.
    So what settings, camera and flash, do I need for the following:-

    1. Lovely day, bees etc buzzing about. Using either 90mm or 70-300mm at 300mm at a Rep. Ratio 1:3, need SB800 to supplement light in Syncro-sun mode and stop insect in flight.
    2. Same type of thing but as a normal close-up BUT INSECT STATIONERY. ie. Straightforward portrait.
    3. Dragonfly going like the clappers at 30-50mph back and forth. Flash possibly needed again as supplementary lighting. Problem with this is the distance from camera to subject. Could be 40ft+ so the use of the SB800 may be immaterial and I will only be able to do this with high ISO's and fast shutter speeds.

    For 1.and 2. I think I need MATRIX metering on camera and iTTL Balanced Fill-Flash but to be honest I am very confused. Mainly because I equate HIGH SHUTTER SPEEDS with stopping the action.

    For examples of my work see my last post in Macro under 'More of Bobs--
    on or around the 8th April plus the following 2 pictures.

    If you have any questions that you want answered to help clarify my work/request, then you can, if you wish, email me direct. Might save clogging up this forum.

    Many thanks. Bob F.
