Figure 2, below, is a somewhat less "doctored" image that Mr. W also believes shows RCC damage. This image may be too dark for some monitors so I'll clean that up on the next page. For now, though, observe the resolution of the image. The resolution of this image is far greater than that of the original NASA STS-107 image.
Figure 2.
In comparison to figure 2, figure 3, below, is a similarly cropped image that retains the original NASA STS-107 image resolution. Remember that these images are highly cropped versions of the original NASA STS-107 image and represent only a very small portion of the original image. The difference between figure 2 and figure 3 is that Mr. W has resampled his image to a much higher resolution than the original NASA STS-107 image.
Figure 3.
In figure 4, below, I have taken the tiny cropped image of figure 3 and enlarged it (as opposed to resampled it) so that it is approximately the same pixel dimension as Mr. W's resampled image of figure 2.
Figure 4.
Note the "granularity" in the image. Each small square in the image represents exactly one pixel in the original NASA STS-107 image. It should be noted that whenever an image is resampled to a higher resolution, as Mr. W has done, the image processing software (in this case, Photoshop) applies interpolation and smoothing algorithms to the image. There is a limit to the amount of information that can be extracted in such a process. While photos that have been resampled to a higher resolution often look better to the eye, it is not necessarily true that small features within the image, such as Mr. W's "gash", are enhanced accurately. On the next page I will increase the the brightness and gamma in these images.
