Lensbaby

I'm pretty new to photography, and am going to Disney World next Friday, I bought the Composer, Optic swap and creative apertures. I need to know what is my best bet for the fireworks....what setting etc. Thank you!!!

hi, assuming you know the basics to photograph fireworks, check here some basics if you dont know.
Regarding the Lensbaby specs, if i were you i would try out first the creative apertures with city lights or such, to see what pleases you. Are you using the creative apertures that comes with the pack or are you cutting them yourself? Keep in mind that the less light that the aperture design has (also the lower the F, the sweet spot of focus decreases in Lensbaby). if the design of the custom aperture is a equivalent, lets say F5.6 the balance between the shutter speed and the sweet spot should be enough to get a sharp image on the sweet spot and the creative aperture "bokeh" in the out of focus area. so if, lets say you are taking a photo with a shutter speed of 1/250, the aperture needs to provide enough light.
Summing it all up its a balance between shutter speed, aperture design and the fireworks burst duration.

hope it helped to shade some light on the subject.

also, dont forget to bring a tripod with you.
