umbrella size for my light

[m_mphotography]

Okay, so this maybe a real silly/noob question but I'm going to ask it anyway. I have an SB600 speedlight and I just purchased an umbrella to use for reflective light as well as for a shoot through. I'm wondering if 45" is too large for the speedlight I have...any input would be greatly appreciated.

thanks

No, that size isn't too bad, but any larger and probably too big. You should use your wide angle deflector to spread the light as much as possible when bouncing since the umbrella will reflect a small sized light if you zoom it and negate the purpose for the umbrella in the first place.

When I use my studio strobes, I use them barebulb to get the maximum light spread before bouncing, which makes it softer and somewhat directed.

yeah that's decent size if you want to light half or 2/3 of the body is fine but full body shots you need bigger umbrella. or higher out put strobes

I probably would not go much bigger than 45" because there will too much light distribution thus too little light. I read that 36" is about perfect for the SB600 and that a 24" will provide good intensity. If you go much bigger than 45" you might need to step up to the SB800 or go for full studio lighting.

I will be interested in which you get and how they perform for you. Maybe one day I will follow your lead.

Good luck. -G
