Try putting something behind them other then the wall, I have the same problem with my camera sometimes, if the wall is heavily textured the camera will want to focus on that instead, that's what it looks like happened here.  If I'm having that problem in a shot, I usually throw a piece of paper or an 18% grey card in between the model and the wall.  Also, throwing more light on the subject helps.

well, in fact it is not back lit.  it is just paint.   ite enterprise and federation class is just testors light blue, but on the inside of the dome, then simply snapped in place.  then shot with a blurry camera.   the ascension class , since the sensor dome is resin cast, is testors gold leaf, applied with a q-tip. then filmed with the same blurry camera. 

Looks like your fleet is growing by leaps and bounds. Some impressive work, there.

The deflector dishes seem to "glow" blue almost as though backlit, though I assume they're not. If it's a paint effect, it's great. How did you do it?

Also, a well-meant suggestion: if it's do-able, try taking some photos outside under natural light. It might sharpen things up quite a bit.

Thanks for sharing your projects!

Nice looking models though a little blurry - I think it's the warp fields messing with your camera.

Next time take the photos when they're running on impulse 

I know what you mean, sometimes my camera wants to focus on anything but the model, I guess I need to learn how to use the manual setting someday!
