Andy Perrin Posted September 20, 2019 Share Posted September 20, 2019 I mean, they call it "red meat" for a reason, and apparently it is also infrared meat. An accidental discovery while playing with my 980nm bandpass filter. Sitting on an incandescent flashlight with two pieces of printer paper on top for a diffuser: Link to comment
colinbm Posted September 20, 2019 Share Posted September 20, 2019 You can sort-of X-Ray your hand with a torch, so no surprise here.Have you photographed your hand covering the lamp ?Col Link to comment
Andrea B. Posted September 20, 2019 Share Posted September 20, 2019 Well, we don't see topic titles like that every day! You could also try some slices of ham or bacon? Would these kinds of things fluoresce? Meat slices, I mean. Link to comment
Andy Perrin Posted September 20, 2019 Author Share Posted September 20, 2019 Andrea, the filter is at the water absorption peak, so I would have to use either another filter or dry the meat first. No idea about fluorescence! Colin, I don’t think I’d see through my hand, this filter was for the water absorption peak, and hands have water in them. Link to comment
dabateman Posted September 20, 2019 Share Posted September 20, 2019 I think what Col ment was if you take a flashlight and hold it to your finger or hand it looks like your 3rd and 4th images. I also think whst Andrea is saying is it would be nice to have a steak with water, next to a piece of jerky without water to see the contrast. Link to comment
Andy Perrin Posted September 20, 2019 Author Share Posted September 20, 2019 I understood what he meant, but you can see the visible light photo yourself. The jerky is far more transparent in IR than in visible. (Although it does have some transparency in visible.) To do the steak experiment, I guess you'd need to take a thin piece of steak and test it before and after drying, or else it wouldn't be a fair comparison since it depends on thickness and composition. This was store-bought jerky. Link to comment
dabateman Posted September 21, 2019 Share Posted September 21, 2019 I wonder if mushrooms would be similar.You can easily dry mushrooms in the oven on a cookie sheet at 200F for around an hour.See a before and after dehydration photo. Not sure if a steak is easily dryied. Check the lowest setting on your oven. Link to comment
Cadmium Posted September 21, 2019 Share Posted September 21, 2019 Are you sure it is real meat? Not just some colored meat byproduct made to look like meat? Link to comment
Andy Perrin Posted September 21, 2019 Author Share Posted September 21, 2019 Haha, Cadmium. I am reasonably sure although I didn’t do any testing (no coloring is listed in the ingredients). Link to comment
