Shoot through umbrella size?

[anth_333]

Hi all i just purchased a 33 inch white shoot through umbrella but I didn't think about the size before i bought it :P.

Just wondering if 33 inch is enough for an outdoor model shoot?

The size of light source relative to the size of the subject determines how soft or harsh the shadows are. So, technically, all sizes can be used on all subjects, but you are limited in the degree of softness you can achieve. Shoot some test shots, if the shadows look good, then it's big enough! If you wish the edges weren't so defined, then you need a bigger one.

Oh okay and i was looking at the reflector type of umbrella also, the one where the light bounces into the umbrella. Is there a difference with the light is one better then the other?

Look at response #21 in that thread; the reflective set-up using the 46 inch Photek Softlighter II shows fall-off on the 45 degree axis as: 100%, 90%, 80%; along the same 45 degree axis at the same measuring distances, but in shoot-through mode, the fall-off measures 100%, 70%,40%. The SAME Photek Softlighter II was used in his tests because it can be used as a reflective, OR a shoot-through, OR as an umbrella box, making it a Triple Threat design.
