Testing fireplace flames for Rest, Relax, and Reflect. Got a little out of hand with those particle numbers.
After staying after school many times, I finally remembered my camera to take some close up photos of speakers and microphones, oh, how inventive :P
I just received my EOS 7D and ef 50mm f/1.8 in the mail today. :D I've been saving up for this camera since September. I'm so excited! I didn't so much look through the settings, so it was on single shot autofocus for this image and the ones following it. I have much to learn about this camera. :)
My setup for testing the Canon 100mm F/2.8 Macro USM against the Tamron 90mm F/2.8 Macro. Verdict: Both are insanely sharp. Optically there's zero difference between the two lenses.
I got a job. At a hospital. I had tests taken today..it took all day.
Update.. there was an issue with me not having a shot that I'd need to have to work there. I decided I didn't want the shot and so gave up the job.
Testing an AVR controlled triac based dimmer circuit. This test used lower voltages and isolated power supplies but the real thing will be partially mains connected. Control parts are optoisolated for safety.
Testing focus at f32 to compensate for any errors. I'm really impressed with how sharp the Fujinon 125mm lens is! It seems to have a lot more contrast and sharpness than any other lens that I have used before. Time to try it out on proper film now.

Formula One Testing, Bahrain Test Two, Day Three, Saturday 1st Match 2014. Sakhir, Bahrain.
So I was feeling a bit bored, and at the same time, I wanted to test out my freshly made "Solar Lantern".
Anyways I saw some online instruct-ables on how to build a cool solar light. So I went to ikea and bought a mason jar, and borrowed the electronic parts, and put em all together.....and voila! A solar lantern.
Anyways, for the real test. I wanted to see what the difference between using a skylight filter on the amount of light it actually blocks. When I first bought my camera a while back ago, I was naive and didn't know better. The Black's employee convinced me that I needed a skylight filter to protect all my fancy lens from getting scratched. So I bought 2 OPTEX SKYLIGHT FILTERS (52mm). They were $14.99. Then I recently read an article online that cheapo filters (this one), actually blocks out a lot of light.... but how much worse?
So, shown here are 2 different photos. One WITH the filter (top), and one WITHOUT the filter (bottom).
Can you see a difference in the amount of good light that gets filtered out? These are identical exposure values for both shot, and haven't been edited in any way. Also note the reduction in sharpness.... I'm sure as hell not using these craptacular filters anymore.
Rebel T2i Test video - 1080p Video.
Shot this with manual focus using the 60mm f/2.8 macro lens at ISO 1600.
See lots of promise here :)
