Many writers love description. They think the more words they throw at something the more precise they can communicate details and thus a richer story experience. No matter how much prose a writer uses to describe something it will never match the power of an actual image. If you need to relate those details to an audience you should show them pictures instead of trying to recreate the picture in their head with words.
It could mean your short story needs to be a short film or it could mean you should add some pictures to the novel you're writing, but you should not spend time fighting the nature of media rather use each for best effect.
Physical Setting
Not only are there too many details in a typical landscape to commit to paper but a detail important to one person may not be important to another. What you as the writer feels is crucial to get across to a reader may not resonate for some. When you show a picture each viewer of the picture makes their own decision as to what parts of the image are important and it will make the experience more personal and relevant.
Physical Things
Just as a landscape is hard to translate to words, so it is with physical objects. If it is important to you as a writer that your audience see what you see then you should show them the images and not your interpretation of them. Often writers resort to using the actual technical term for an object thinking that it will do it but for people that are loath to reach for a dictionary or do not have much life experience that word will mean little. To young people a record is a song and that song is probably an mp3 or CD, to an old person a record is a small vinyl disc that music was put on. A picture of the record you are referring to removes equivocation.
Appearance of People
You cannot draw people with words. You will only point out in an amorphous manner the few features you as a writer find interesting. The description of faces in particular is loaded with words like aquiline that is general and does little to evoke a nose properly. If you do not wish to convey just what a person looks like then use words, if only the real thing will work for you then you need a photograph or good illustration at least.
Physical Actions
If still images are hard to turn into words then actions are exponentially more difficult. If "he walked to the store" and it does not matter how then use words. If this character has a very specific walk and the walk was filled with fits and starts then nothing less then motion pictures will convey this. Rather than filling pages in the hopes that people understand what you mean do them the favor of showing it.
This is not just an exercise in putting the right thing in the right medium. Visuals should be show in images not just because it will communicate more effectively but it will also enrich the rest of the experience. Once you have seen a character in a photograph any subsequent actions this character performs will be much more vivid as your brain does not labor to create physical details of their body and can just animate the photograph. Just as it is more poignant hearing stories of people we have met, it will be a more gripping story the more we see.
