I am contemplating between shoot-through umbrella and reflective umbrella for product photography. From my research shoot-throughs diffuse light more producing softer light but less focused than reflective umbrellas giving more contrast. Reflective umbrellas provide more focused light that "wraps" around object's sides and reduces shadows.
I am talking about shoot-through umbrella with white fabric inside and reflective umbrella with white fabric inside and black fabric on top. And while both have their uses I want to know what is more preferable for product photography.
Should I get 2 33" umbrellas or 1 43" umbrella? Maybe I get one 43" hybrid that has black removable fabric and serving either as shoot-through or reflective umbrella to see what works better? I also did not mention that I have 160 LEDs 5400K video light and another video light with 5400K. Would having them and 1 43" umbrella be enough for this?
Finally light bulbs. If I choose to go with 2 33" umbrellas, would 45W bulbs be enough? If I choose 43" umbrella I have notion that at least 65W bulb should be bought for it.
Thanks for help
