I may have touched my Einstein bulb.

How can I test it to make sure it won't blow up on me when I need it? I've fired off a few flashes at full power and it seems okay. Do I need to "stress test" it some more?

To be safe, clean the surface of the bulb using rubbing alcohol and let it dry on its own (really quick). It'll remove the oil and won't leave any residue.

What should I use with the rubbing alcohol? Any clean cloth?

I have never shot with studio strobe before, for christmas this year I got a Alien Bee B800 and some Cybersyncs. This is the very first photo with the B800. B800 @ 1/4 power with a 64inch soft silver PLM and diffuser. This is un edited and straight out the camera, with the exception of a resize for this forum. Comments are welcome.

Thanks! I was trying to focus on the tree and hope that 5.6 would be enough to catch all in focus. I should have gone to F11 and increased the power on the strobe.

why not just focus on their faces?

remember that DoF is half in front and half in back of focus point.
If you wanted both faces and tree in focus the focus point should be about half way back on the head.
Maybe an ear or the arm going behind the girl. You can get an idea about DoF by looking at the woman's necklace, boy's tee shirt, etc.

Woman has some bright highlights on her forehead and cheek, while both the kids have nice smooth skin tonality. If you remember how you had the PLM aimed that will help you in the future with feathering to minimize the bright highlights. They tend to be on the person nearest the light, especially if the light is aimed a bit toward them rather than feathered to the other side of the group.

The light was at camera left about 6-7 feet away from subjects and about 6.6 feet above subject and tilted down toward subjects.

Always love pics with interesting uses of gels. One problem for me, (it may be just me! I'm a guy... :P) but my eyes go straight down since her crotch area is basically saying "look at me". well that's for me. I may just have a perverted mind or something. At least I'm honest.

... I think I need to seek some professional help

May just be a guy thing lol..

I wasn't going to say anything so as not to come off as a prude, but crotch shots, IMO, never work well. In this case the highlights on the wrinkles of her leather or leather like pants makes it even less becoming.

Going back for another look, the composition really does bring all the visual focus to her crotch, and the logo placement reinforces it.

I also am not a fan of the "pulled" processing look. I think it muddies the image.

The use of gels is interesting.

I tried to crush the shadows somewhat to take some detail from her crotch area but didn't want to go to far and ruin the rest of the image. Thanks for the insight on logo placement, going forward I will definitely keep that in mind.

.

Actually it's more like 1/3 in front of the focus point and 2/3 behind.

Any clean cloth will do. As long as the cloth itself isn't covered in oil itself haha
