My DIY Led Lights

[Scott Pultz]

I have been working on some DIY LED lights. Here is my first test compared against a fairly expensive commercial light. Before I expose which is which, what do you think in comparison? The exposure and color temperature are not identical between them so it was a little tricky getting them to match. They do seem pretty close though...

Please pardon the lousy photo. I'm also chasing around my baby as I do this haha

P.S. For best quality you probably want to save the images off and open them. In my browser the image showing up on the left is actually b.jpg. I should have labelled the images themselves, sorry.

And here is a reference with a quartz bulb at about 2800k. It pretty much trounces the LED when it comes to red. I can see why people like Tungsten so much. Perhaps I should just go that route...

Doing some color correction I'm able to get the LED surprisingly close to the quartz bulb. I'm going to try Resolve next and do more fine tuning. So perhaps the LEDs will be workable, but the incandescent is better out of the box.

When you think you have it close, light one half of a face with the tungston and the other half with the LED and see what you get.

I also have a few other candidate LED chips coming this week that I will be testing.

I have done some more testing with my BMPC. With the quartz bulb my skin appears too red so I suspect IR pollution. With the LEDs my skin looks pretty close to how I see it with my eye. Also with just color temperature controls I'm able to perfectly match my DIY light with the commercial one, which is pretty sweet
