I can now achieve a quite a bit more than I could with my £3 daylight bulbs Im struggling to get evenly blown out backgrounds though, the lower half of the photos are always darker. Any suggestions?

A few pics from today:


I can shoot moving things too, which opens a loads of new doors

Where are your lights relative to the item you are shooting? I'd guess if they are above you will get lighter areas at the top of the image.

There is white card inside the light tent, which is cleaner, whighter, smoother and brighter than the material the light tent is made from. The card curves and turns up behind the product.

I have tried moving the lights around. Currently, they are in front of the object and slightly to one side. The tent was supposed to come with a 90cm brolly, but came with a 125 (or 120?) cm brolly instead - its massive! Bigger than the entire tent. I guessed this would be good, as lighting would be more diffused, spread out and softer (thus reducing the effect of shadow further - am I right?)

My lights are on stands which have a minimum height of "fairly high" (not sure how high, but far too high for 100% frontal lighting, they shine down on the tent somewhat)

I turned the contrast up more than I usually would have done, and will be removing the noise as soon as I get a PS plugin to do so. I have more light than I've had in the past, which is good.

The larger umbrella will be giving you a more diffuse light. It looks like a light falloff problem to me, but you'd think with shooting using both umbrellas and a tent that the light would be evenly spread. I'd suggest using a flash meter to measure the amount of light at different heights inside and outside the tent to get an accurate idea of light levels.

As you can't drop the lights down you could try putting your table on a few bricks to move it further up towards the lights, that would allow a shallower angle for the lighting. Also try without the tent to see if that makes a difference.

I'll see how I get on, and will try proping the table up a bit. And I'll no doubt be back with more questions about meters (sounds like a good idea) sometime soon.

Let us know when they get one for 6 ASA - it'll be nice when they're up to about the C19th!

Please forgive my utter ignorance, but which or where is the noise on either of the pics ?

The only thing I thought I could see, turned out to be a bit of crap an my monitor.

I believe it's a joke regarding Rob's (justified) obsession with noise.
