I've been facing a few questions in my mind about the terms image processing and image editing. What is the difference?
In short, in practical use, it's very blurry and there is a lot of overlap. From that discussion, though, let me show you the descriptions we've arrived at for various related tags:
Post processing is the process (and art) of adjusting a previously-captured image to obtain a desired look. It encompasses everything from simple whole-image adjustments to detailed per-pixel touch-up work.
Image processing is the computational transformation of an image signal. It's about the technical side of batch transformations, conversions, and enhancements, as distinct from post-processing (adjusting an image to achieve a desired look, probably using image processing).
Photo editing is the process of reworking an original photo, either produced by film or digital, to create the artistic vision of the photographer.
You're asking about "image editing", which is none of the above, but I think we can extrapolate. Crucially, editing has at least some of the implication remaining from the actual job "photo editor" — see this description from Wikipedia:
... a professional who collects, reviews, and chooses photographs and/or illustrations for publication in alignment with preset guidelines.
So, in one sense, photo editing (and by extension image editing) are the things one might do along those lines. But, clearly, in common use, we also use it to mean "all the stuff one can do with Photoshop".
Likewise, image processing has implications of its own, this time of signal processing. Again from Wikipedia:
... image processing is any form of signal processing for which the input is an image, such as a photograph or video frame
So, from a technical point of view, the term image processing leans much more towards the technical side, and barely what humans do at all — as our tag definition above says. But again in common use, this is used very interchangeably, and if someone referred to their work in Adobe Lightroom as time spent on image processing, we'd all understand.
Well, basically Post-Production services are required for processing film, videos and photography. For making motion pictures, videos, animation etc. From Wikipedia, Post-production, or postproduction, is part of the process of film-making, video production and photography. It occurs in the making of motion pictures, television programs, radio programs, advertising, audio recordings, photography, and digital art. It is a term for all stages of production occurring after shooting or recording individual program segments.
Image Processing is kind of image conversion. For example, image to vector, raster to vector, jpg/png/bitmap to vector etc. These services allow you to get the desired color, shape, size and quality.
And Photo Editing is just altering your image applying some methods for example clipping path, background remove, photo manipulation, photo restoration, image enhancement, color correction, image optimization, photo retouching, glamour retouching, image masking and deep etching etc.
Semantics... and absolutely nothing more. The meaning of each depends on who is using the terms and there is a lot of overlap between the generally accepted usage of the two terms.
