Chris wants to talk about the technology of a digital camera. Every DSLR camera has a bump on it and that houses the penta-prism or penta-mirror. The electronic viewfinder is also in there. Why does an electronic camera still have a mirror? Well, mirrorless cameras don't have the mirror array, but they do have a viewfinder. A DSLR needs one to bounce the image in order for you to see the image, and the prism makes sure it shows up right side up. When it's mirrorless, then the camera doesn't need to reflect any image, it just broadcasts it to an electronic viewfinder. So they can be smaller and lighter.

Don't forget our current assignment: "Shadow." Take a photo of, about, or otherwise concerning the concept of "Shadow" and then post it to the Tech Guy Group on Flickr. Make sure to tag it with the word "Shadow" as well! And if Chris likes it, it could end up on next month's photo contest review segment!
