The most common means of storing pictures for easy display is in a photo album, but an album does not provide true display of pictures, since they are not actually being shown until someone opens the album. Placing pictures on display means making them visible by exhibiting them in some form, usually by framing prints and placing the framed pictures in a suitable location. Your best or most memorable pictures will almost always display better if they are first enlarged. The size of enlargement is governed by the size and quality of the original negative or slide, by how far from the viewer the print will be when displayed, and by the amount of space that is available in the display area. Most sharp 35 mm pictures that are blown up to these standard sizes will properly show detail with little or no apparent graininess.
Image quality is the primary restriction in picture size when it comes to enlarging photographs.
Negatives must be sharp. Be prepared to pay more for custom work by a professional photo lab. The results are usually worth the additional expense. If you are constantly changing pictures in your display, as on this studio wall, push pins are sometimes the best answer. If you plan on displaying unframed prints on a wall that is curved, be sure not to have them mounted.
