Home light-box lighting

[chief]

I've been working on a small light-box which I constructed using a cardboard box. I cut out the sides and made two large windows which I covered with tracing paper to diffuse the lighting. On each side I have a 150 watt type A soft white bulb. However the lighting in my pictures is a little lower than I expected.

Here is a shot without my camera's flash:

with the flash:

I would like to make the lighting to something like this as seen here:

I am wondering also if the lighting in that picture was adjusted with software or if that was the true light in the studio.

All you are finding here is your lights are tungsten, change the WB setting or use flash on your home made box, lightbulbs are not ideal for photography. H

PS. good results can be achieved cheaply using halogen lights, available from builders merchants or DIY shops. H
