It's not what I've observed, but I definitely can imagine how settings for the compression, or what the algorithm concentrates on, could make that happen. Oh now I understand what you're saying - that makes sense. (It's Okay to Be Smart on YouTube has a cool video about Infrared )
They way different surfaces reflect light in different wavelengths help scientists classify things on Earth and Mars and all over the solar system. This same process is used by satellites as well to measure and classify things on Earth from space. When you combine these you get an image that looks pretty similar to what it would look if you were really there (It's called true color and false color ). Take the 525 nm or 550 nm sensor and make them green and the 675 nm sensor and make them red. You take the 440 nm sensor and give each pixel a value between 0-255 and display that with more/less blue. They can use these images to create color images. The Mastcam on the curiosity rover is actually two cameras with various sensors for different wavelengths (including wavelengths outside the visual range). For example blue is in the 450–495 nm wavelength, green 495–570 nm, and red 625–740 nm. The colorization is done by taking several of these images for wavelengths and adding them together. The images are really just the wavelength reflection intensity measurements (think of it like RAW images on a DSLR but for more than just RGB). Each camera has specific sensors for different wavelengths of light. The cameras on the rovers are not the same as the camera on your phone or a DSLR. Like another crows has pointed out, they do work into writing a script, the narrator, and editing the material, so that's not a take I like (and I'm also "in the same business" as them). I wouldn't have liked the SR-GAN approach either, I'm not a fan of it (to me it trades accuracy for good looks, and it introduces some artifacts which, while harder to spot on video, are probably not really there).Īlso others have pointed out that it seems like basically monetizing public domain images without putting some effort into it. And no, they just took the images and pan over them.
When looking at the title at first I thought they had used an SR-GAN (or modern variant) to upscale the images. It's not the first time someone has rendered them in 4K video (I'm pretty sure Astrum and Scott Manley have used some of these images before). It's not the first time this images have been seen. Some of the bashing is because of the over-the-top narration, and the script saying things that are borderline lies.
