    I made a quick test: one shot without filter and the other with a TD filter.
    The background is a light green micro-fiber cloth.
    The immage was scaled-down, nothing more, no adjustments.

    The diferences are less dramatical as with color though.

    What's a TD filter?
    Heavily sedated for your protection.

    Some more comment about hot lights and macro photography ... I remember years back reading a tale of woe where some guy set up lights to photograph stuff on his model railroad. As he tinkered around composing and metering, he was dismayed to see some of his plastic models beginning to sag before his eyes!

    One needs to be a little careful with hot lights, halogen or photoflood. I am a mere hobbiest and not shooting for commercial color work, so maybe what suits me isn't up to serious pro work, but I have currently abandoned hot lights for daylight color temperature compact fluorescent bulbs, mostly in soft boxes. I haven't shot a whole lot of color film with that rig, but what I have shot looks good to my eye. The bulbs are pricey, but assuming they're not dropped, last a long time and are much cooler in operation as they use way less power.

    Another .016 ¢ (after taxes)

    Sorry guy's, the TD filter should have been mentioned as a FL filter, with halogen-daylight I had even less diferences.
    Tubelights were used reading : +20M etc

    Peter, the FL filter converts Fluorescent tunes to Daylight balance so is innappropriate for Tungsten halide bulbs

    Don't think flash is safe in macro photography though. I have seen steam come out of bugs that were flashed at close range. Horrific way to die.
    Flash units too can put out more power, and heat, than would be good for many things.
