    Default Studio Lightings :- How to remove hot spot?

    recently ive been appointed to shoot some on site glamour.
    But for one shot, it had very terrible hot spot... i thot her face was oily, thus i touched up using a blotter on her face... but still e same wor...

    den i put the tracer against the strobe light... though it lightens a bit of the hot spot, but its still there....

    since it is a on site shoot, i canx possibly use PS to rectify it... what shd i do?
    use a bigger umbrella?

    increase the distance btw tracing paper and light... no space then try another tracing paper in front of the 1st tracing paper... a little distance in btw too.

    A diffused light source placed far from the subject would result in almost the same harsh effect as a direct light, less the brightness. The shadow behind the subject gets harsher as the distance increases between the diffused light and the subject.

    The key is to put a diffusing material of a larger surface area nearer to the subject rather than right in front of the light source.

    Try cutting out a huge piece of diffuser and drape it, using a C-stand or similar, near the subject with your strobe some distance behind it.

    And changing the angle of the light may help to cut down on hotspots too.

    i dunno about studio photo shoots but i do video/film lightings. what i do to reduce hot spots are:

    1. add diffusers/tracing paper.
    2. increase subject-light distance (but one more light may be needed to maintain light intensity).

    hope this helps...

    Umbrellas, softboxes, etc are called light modifiers(american terminology) as they modify the light.

    Maintain the same distance between your strobe light and subject but drape a large piece of diffusing material nearer to the subject rather than right against the strobe light? I sometimes use this technique for my video production, in my case it would be a continuous lighting source instead. However the concept can be applied here too, I believe.

    Since you used an umbrella with an extra layer of translucent material acting as a diffuser, then, I suspect it is the subject's skin complexion. Varying the angle of your light source together with varying the pose, besides using oil blotter as you did, would minimise, if not remove hot spots.

    i jus remembered.... becos the lightings were placed and i did 1 test shot.. no hot spot on my first model's face.. but when i shot the 4th client.. oh gosh.. hot spot was so obvious.. i think its the makeup tt is giving problem...
    cuz my makeup artist actually used the liquid foundation on her.. which will cause a bit of glow on e face.. other than tt.. the rest of the pics turn out ok...
