A simple method to use PS to optimize digital photos – landscape color correction

A simple processing method for optimizing digital photos using PS. Photos taken with a camera are subject to many factors, so it is not always possible to get perfect photos directly, even by professional photographers. When the film taken by a traditional camera is developed into a photo, if the effect is not ideal, it must be corrected during this period. If you want to scan the film into an electronic image to facilitate editing and online communication, post-processing adjustments are also required after scanning the film. Non-professional digital cameras (DC for short) are very popular photography products nowadays. Their shooting effects are affected by more factors, because most photographers are not very skilled, and some of the functions of this type of camera are relatively single. The effect itself is not good enough. Coupled with the shooting environment, weather and other factors, the effect of the original digital photo is often greatly reduced. However, if the photo is printed into a photo, the effect will not be bad, because the output photo is adjusted and photographed at the same time. Paper characteristics, etc. will optimize the effect. Nowadays, many digital photos are exchanged online, or made into one’s own electronic photo albums. When compared with each other, the contrast between those with poor results is even stronger. In fact, with a few simple adjustments, you can make the faded photos look better.
