Hello all. I'm hopeful to get some help/explanation for what's going on here. Thank you in advance.
The image below includes screen-shots of both the .dng (upper) and the .jpg (lower) from a M2P. They were combined into a single image for ease of comparison. The camera was set to record both raw & jpeg in a single shutter button push.
.
These photos were loaded into darktable (a raw image editor) & screen-shots taken before I made any adjustments. Any processing performed was done by darktable on it's own. The first thing you notice is that the raw image has some fairly bad barrel distortion that the jpeg does not. Then you notice that the raw image has a wider FOV than the jpeg. darktable reports the raw image with dimensions 5568 x 3648 and the jpeg as being 5472 x 3648 (which are the camera's specs).
.
The Microsoft Windows 10 viewer as well as some other viewer apps seem to be opening just the Reduced-resolution image (jpeg?) embedded in the raw file and do not show the increased FOV as shown in darktable. However, CyberLink Power Media Player opens the original .dng file and shows the barrel distortion & 'bonus' FOV and looks exactly like what darktable shows. Is the camera/software causing the distortion??
.
The raw file is almost six times the size of the jpeg so much more data is available to potentially yield better pictures but the distortion is unacceptable. Any help appreciated!
