Yep. Looks pretty 'crispy'.
There are no "pure, clean" photos.
If you shoot Raw files
Today's standard
CMOS pixel (active pixel sensor) consists of an analog photodetector (a pinned
photodiode), a floating diffusion, a transfer gate, reset gate, selection gate and source-follower readout transistor. The whole shebang (pixel) being known as a 4T cell.
The light energy the analog photo detector is recorded as an analog voltage.
When the analog voltage is 'read' it's amplitude value then gets converted to a digital number.
Note that pixels cannot record color.
Pixels can only record gray scale.
Because of that in front of the pixels is a
Color Filter Array (CFA). Using the layout of that color array a Raw file converter interpolates what color of light each pixel recorded - a process known as
Demosaicing - using the camera's built-in firmware or an external Raw conversion application like Adobe Camera Raw (ACR), to produce a 16-bit depth
Raw image data file.
In addition the data file also has to have a gamma curve applied that matches the human eye non-linear response to light as opposed to the linear response of the photodetector that is the heart of a pixel. Some sharpening and some tone mapping is also applied.
The situation is such that each Raw converter application, be it in-the-camera firmware or an external application, renders a Raw file according to it's own unique set of algorithms.
If a photo is made in the camera as a
JPEG file the in-the-camera firmware first rendered the Raw file the image sensor (pixels, signal amplifiers, and analog to digital converter) made, and then applied the lossy, compressed changes that are the basis of the 8-bit depth, ready-to-print JPEG file type making the output image way, way less than "pure, clean".
DSLR cameras have user changeable in-the-camera settings that additional edit the JPEG file before it is written to he memory card in the camera, thus making the final image even less pure and clean.
Raw files are not ready to print and require post production 'finishing' (editing).
