Image restoration and enhancement techniques offer a powerful tool to extract information on the small-scale structure stored in the space- and ground-based solar observations. I will describe several deconvolution techniques that can be used to improve the resolution in the images. These include techniques that can be applied when the Point Spread Functions (PSFs) are well known, as well as techniques that allow both the high resolution information, and the degrading PSF to be recovered from a single high signal-to-noise image. I will also discuss several algorithms used to enhance low-contrast small-scale structures in the solar atmosphere, particularly when they are embedded in large bright structures, or located at or above the solar limb. Although strictly speaking these methods do not improve the resolution in the images, the enhancement of the fine structures allows detailed study of their spatial characteristics and temporal variability. Finally, I will demonstrate the potential of image post-processing for probing the fine scale and temporal variability of the solar atmosphere, by highlighting some recent examples resulting from the application of these techniques to a sample of Solar observations from the ground and from space.
