Diffusion

I'm still in the learning stage. I have been experimenting with the Rosco diffusion sample kit of 15 gels, using an egg as a subject. I see almost no difference between the various gels. Is it that subtle? Am I doing something wrong? I am using a Home Depot light with homemade barndoors, 250 watt.
 
Do you have halogen bulbs or those blue-tinted ones? The blue-tinted ones will be better for this, as they send out white light instead of yellow.

How'd you make the barndoors? I have the homedepot lights too. I bet there's a DIY thread on them out there.
 
What gels are you using? There can be very subtle differences to your eye, but a lot of difference to the camera. Also work lights light spread is so uneven that you may have a hard time telling anything about a gel diffusion on them.
 
The size of the light has more to do with the softness of a light than the diffusion in front of it.
 
Use something other than an egg as your subject.
A surface that is white, smooth, and void of edges and angles is not a good subject to see the differeces in how diffusion works. Especially for someone just starting out with lighting. Use a subject with depth and contours.
Try the head of a mannequin or doll.

Agreed. You're going to see the effect of the diffusion more clearly in the way that the shadows work than you will the highlights.
 
ya dude. egg not a good subject. Also the further the distance that the diffusion is away from the source the softer the light.
