You also don't need to soften the background light, you can hit it with your direct bulbs.
"1/2 stop over" means you want the background to be brighter than the foreground object by at least 1/2 stop, preferably a full stop. A stop is a measure of light hitting the sensor.
If you expose the background correctly, you'll still be able to see detail in the white drop sheet. You don't want that. So you want more light hitting the backdrop than is hitting your subject. Now when you expose correctly for the subject, the background will be overexposed. That is what you want for "high key" or white backdrops where you want to isolate the subject.
Anyway, you're getting it. Play around with your lights more so you don't have to do so much processing and you'll be there.

If you post your camera gear and what mode you shoot in, I can give you some better advice, but basically it means closing down your lens aperture so you get some parts in sharp focus and the background goes softly out of focus.
If your exposure is correct at f/8, turn down your lights and get the exposure correct at f/4.... now see what that did to your focusing area and how it highlights what you're focused on.
All those photos i posted were taken before i read your post. You musta posted that first bit of advice like within 5 minutes of when i went and spent like 2 hours taking shots of my GPU
So i was only able to take your advice as far as processing the images. Next time i shoot (probly later today) i'll definitely pay alot more attention to the lighting setup.
I have an Olympus Evolt E-500. I only have the 2 kit lenses for it. I use the 14-45mm 1:3.5-5.6 for every photo i take. I always use manual shutter/aperture so my settings change constantly from shot to shot. I'm extremely new to anything photography related. I only bought this camera because i was starting to feel embarassed about trying to manage a build log with my Samsung Galaxy S3.
When i'm taking pics of my chassis i usually use f22 or f16. Last night i was going with the lowest aperture i could for most of the GPU shots. Some of em were probly f9 or f11 for some of the shots with more area to focus on, but most of em were between 4-5.6.
Also, the lights don't dim. Just on & off switches. 2 have white umbrella diffusers, and one's real short with no umbrella. The bulbs are 45W 5500k, but i have some 85W 6500k's being delivered tomorrow. I ordered the EX-25 Macro Extender for it last week and it just arrived today. Haven't played with it yet though cuz i've been trying to get these 3 dust spots out of my sensor for the past hour.
So as far as the background light....
I have the 2 tall umbrella lights for the foreground lights and a short one with no umbrella for the background light. It seems like the logical way for the foreground lights would be like a triangle with my shot as the tip of the triangle. Where exactly do i put the background light? I was having trouble last night with it washing out the images, that's why i was playing with different setups.
Thanx again for all your help

There's def room for improvement though. If we were judging this like normal schools, right now i'd be studying hard so i can be accepted to kindergarten.
