Its doable but expect LONG shutter speeds because of low out put lights. So use a tripod. 7mm |

Again very doable but the HEAT will be a bitch. So summer time shooting will be a bit toastie. Look at the new compact flo. lights-cooler temps, decent output, workable color temps & long life. If you use the flo. lights go with either tracing paper for diffusion or something similar. Also look at the glass dolphin shot. Check out the confusion the odd reflections create. I might be a little more critical but having been in the photo biz for 30yrs I see the effort creating the image & the image itself. 7mm |

I did a light box this weekend. My one question is if the pictures were edited to get the really white background. My pictures were not that white and that was even after adjusting the white balance and using a flash. Details; Were you using only a flash for your shot? If not what kind of lights were you using? Did you do a preset WB or a custom WB? How did you do your custom WB setup? For instance photographing a black rifle in a white bathtub will require an incident light meter reading to get a correct exposure or use a 'gray' card* for a reflective light reading. If this doesn't make sense to you just ask-there are many more here that can elaborate on 'proper' metering for correct exposures. 
*An ExpoDisc is a cool gadget for custom WB & exposure settings. 7mm |

If not what kind of lights were you using? Using two of the shop lights with the light box which are about 500 watts each. Did you do a preset WB or a custom WB? Switching to the Tungsten Light white balance really helped, but still not as white. How did you do your custom WB setup? Since I am still new, I just happened to read about this. Also that ExpoDisc sounds like it would be a good investment. |

Thanks for the tip. So it just a box with the sides cut and white paper. How ingenuis |
When using mixed light sources w/ different color tempertures & light output you will get funky color casting. Yes Funky Color Casting is a highly technical term but I will try to explain so an arfcommer can understand . Just a weak attempt at humor...still working on my first cup of coffee .
The speedlite will be close enough to a 'daylight' color balance (5,000 degrees Kelvin kinda, blue but mostly white ) & the 500watt work lights are close to a tungsten white balance (3,200 degrees Kelvin, amber color) but most likely 'warmer' (2,900 degrees Kelvin more yellow than amber). Because of the 'color' of the light your illuminating your subject may not be evenly spread out...some warm light (amber to yellow) will be in some areas & some cooler light (blue to white) will be in other areas...you will get the areas correctly exposed to be more neutral & the under/over exposed areas to be more cool or warm depending on what light color is in the under/over exposed areas. Whew!! It's way to early for me to do this but I'm pressing on...
You can get color gels to put on one light source or the other to make them the same color temperture then you can use the 'preset' or custom WB to that one color temp. If you have a SB800 or SB900 they came w/ an amber gel to match the color temp of the 500watt work light...or at least get close enough. So in a nut shell most likely different color's of light are lighting up your subject & the colors are too far apart to be corrected by just a preset color balance so you gotta get the lights closer in color temps or use just one light source type. Now if your 'Ichi Nagato'-name is mostly likely miss spelled- you go for that crossed filtered light effect. Just look in your favorite Peterson's gun rag to see his images. You'll will see many shots w/ a blue gel'd highlight on sone side of the slide & a red gell='d highlight on the other. 7mm Sorry for any miss-spellings-the spell check grayed out  .
