I'd like to express here my opinion regarding NASA (or any other organization making scientific photos and releasing to the public) tampering their
photos.
I've said this in another topic, but it seems very appropiatte also here, so i will make a CTL+C and CTRL-V action:
I agree that NASA many times modify its photos.
But i didn't agree of the reason of doing it, the conspiracious reason.
Tampering the static images is a common proces.
Do you really expect that some images to be EXACTLY RAW images? You know, RAW images may have all kind of artifacts, or not so good
brightness/gamma/contrast.
I will explain that: also i tamper my images (not all, but ussually some of them):
When, many years ago, i began to "digitalise" some of my precious photos on paper, from chemical films, using a scanner and a PC.
Guess what i did..i tampered the images:
- i modified gamma, contrast, brightness, colors or hue
- i removed using clone tool, the scratches, developing errors (white/dark patches)
- i used masks to raise/low brightness on zones (sky, overexposed areas)
- i cropped the 0....255 interval of brightness variations in the low part (dark areas), for example let's say as an example to 10...250,
automatically (autocontrast) or manually (dark level threshold), to increase contrast and remove darky noisy ugly areas
In this days, using digital photography, i also tamper some of the images (the very important ones):
- i modified gamma, contrast, brightness, colors or hue
- i removed using clone tool, the non-desired things, like bugs, electrical strings when deteriorating the atmosphere of the image etcetera
- i remove red-eyes
- i used masks to raise/low brightness on zones (sky, overexposed/underexposed areas)
- i cropped the 0....255 interval of brightness variations in the low part (dark areas), for example let's say as an example to 10...250,
automatically (autocontrast) or manually (dark level threshold), to increase contrast and remove darky noisy ugly areas
- i remove noise in high iso images (which also could make the human skin to appear smooth like baby skin, which i don't want, so i have to pay
attention, or to use masks to operate only on zones (ussually the sky, where the noise is more obviously)
- i remove/reduce chromatic aberations, fringe or contaminations (like the sun/moon/bright areas false halo
- i remove dead pixels (hot pixels) when they spoil the image.
- various other tamperings.
A detailed analysys of those my photos can show easy that those images where tampered.
My reason? To make perfect images from where is not. Am I lying/hiding something in my images? Well, i could say yes, but with a noble reason.
I thing NASA just doing the same with their RAW data when publishing to the world. Nothing more. Also they stitch images and also make projections,
scallings, using monochrome spectrum wavelenghts and compose images from them etcetera.
I bet many people didn't know this normal tampering processes, and they could send me to jail because i tampering my images, if this was very
important to them (i lie to them, no?)
