News Broadcast Goes Green

-


A few weeks ago, I spent some time with a couple of my students painting the back wall of our news studio GREEN! Now, I don't mean green. This color is definitely GREEN! Why on earth would we do this? I still have green paint on my shoes. It was a bit of a hassle, and the color is so bright, it is borderline obnoxious.

We did all of this to take advantage of the chroma key feature in OBS, but even if you're saying OBWhaaaaaa? There could be some good information here. Let's hit a few uses for a green screen, and a couple suggestions for trying to get the same effect on your pictures or videos.

First, the green screen is how you remove the background from live video. While we are painting in the attached video, notice how we seem to be painting an image on the wall? The computer that processed the video took out the green, and replaced it with another image I chose. They film movies, weather reports, sports talk shows... tons of stuff in front of a green screen, and sub in the background that you see. It looks so real, right? Well, okay, some of them look real.

Another use for a green screen is photography. If you take a selfie in front of a green screen, with a little editing in a free program like GIMP, you could be anywhere with anyone. No, I didn't make that up. There is a free image editing program for Windows / OSX / Linux called GIMP. It's sort of like photoshop, but free. I don't mean free to open the program, but $50 to unlock the features. I don't mean free, but they are going to watermark all of your stuff. I mean FREE. 0$. Download and install gratis. There is a bit of a learning curve. This is a full featured photo editor, afterall. Use the worlds second most popular search engine (YouTube) and figure it out.

Wow. Didn't mean to publish this one yet. Anyway, if you're not looking for all the complication of a green screen, or GIMP, or OBS, or any complicated software, check out Photoscissors. It's a free online photo editor that lets you delete the background from any picture (not just green screen pictures) and add in new backgrounds. They also have several other tools available. For real. Go try it out.

That's the real end of this post. Take time to make the world a better place.

Failure is only the end... if we allow it to be.

This morning I got a text message from my daughter letting me know her car didn't start. Naturally, me being a handy guy, I threw some tools in my car to go help get the troubled vehicle running again. After a quick jump start, I was driving around town. I did a little diagnostic work, and decided it was time for a new alternator. A quick trip to the parts store, and hour later, the car had a shiny new alternator. It was great... except, it wasn't.
After installing the new alternator, the problems continued. The car was no better than it was before I had replaced the alternator. This was a disheartening, to say the least. Even now, at 8:00 in the evening, I have been unable to figure out exactly what the issue is with the ailing vehicle.
I am writing this blog while taking a break from researching the problem with the car. After this brief brain break, I will be back at it, pouring over wiring diagrams, looking for clues online, sorting out symptoms and looking for corroded g…

Welcome to the launch of Itsthemitchell.com. If you're here, you're probably lost. It's okay.

This will be the hub for my journey into Instructional Technology. We'll talk 3D printers, drones, programming, tech tips for teachers, etc. This will also be a storage bin for all my staff development sessions.

In the meantime, here is a random picture of me from my phone.


Come back later. I'll be getting some content worth reading soon.

Super Blood Wolf Moon - Let's Practice Photography

I'm not sure if you heard the news or not, but tonight (1/20/19) was a Super Blood Wolf Moon. Super because it is relatively close to earth in its orbit. Blood because there was a Lunar eclipse. Wolf moon is the fancy name for a full moon in January. I decided it would be a great time to practice some digital photography.
Outdoors.
At night.
In 34 degree weather.
This may sound like Greek (geek?) to you. Stick it out. I've just started learning this stuff myself, and would love any photographers to double check my understanding here. The following images were shot on my wife's Nikon D3400. None of them have been edited at all. I do have the raw files, but these are the JPGs. I used manual mode with the shutter at 1/250, f11, 250ISO for the first images. I used her 70-300mm lens fully zoomed in. I let autofocus do its thing. put the camera on a tripod, and set it to snap five pictures after a 10 second delay. As the eclipse progressed, and there was less light available, I…
