Shooting Charming Travel Photos with a Fixed-Focal-Length Lens: 50 mm
Blurring out-of-focus areas (bokeh) is easy using a fast fixed-focal-length (prime) lens with a low f-number. Careful focus on the desired subject blurs the foreground and background to make your chosen subject stand out.
Given the ease with which a fixed-focal-length lens can produce dramatic bokeh, you
                  can have some fun adding deliberately blurred foreground objects to the frame. Including
                  foreground bokeh in the form of fortunes tied to a fence adds both perspective and
                  a story to a shot of a man with his hands fervently pressed together in prayer. 
 Light and compact, a 50 mm lens is perfect for tourists who have to
                  do a lot of walking. Another important bonus is that it is fast, allowing shots to
                  be taken at wide apertures in the dim light under the eaves of a shop. Compositions
                  that leave some space in the direction the subject is looking are better balanced
                  than those that place their face in the center of the frame.
               
At wide apertures, fixed-focal-length lenses can produce dramatic bokeh, but you can
                  also try stopping aperture down to change the amount of blur according to the subject
                  or situation. Shot at the maximum aperture of f/1.8, the pink flowers in the foreground
                  of this scene would be so blurred that their shape could not be discerned, so I instead
                  chose f/2.8 so that they still look like flowers. 
 Shooting at Maximum Aperture to Make Your Main Subject Stand Out
               
Shooting at maximum aperture produces dramatic bokeh. Choose aperture-priority auto
                  mode and select the lowest f-number. Focusing on the brush in the subject’s
                  hand and blurring everything else makes the theme of the photograph clear for an impressive
                  shot that throws the main subject into sharp relief. The subject isn’t moving
                  very much, so choose AF‑S (single-servo autofocus) and take your time to focus on
                  the tip of the brush. 
 Moving
                  the Camera Makes Photography More Fun 
 Because fixed-focal-length
                  lenses cannot be zoomed in or out, the photographer must change positions to change
                  the framing. A single action can be shot in a variety of ways: by moving in for a
                  close-up, tilting the camera down to focus on the subject’s work, or moving
                  a slight distance away to capture their surroundings.
               
Don’t take photos of any one subject only from a standing position; by crouching
                  down or going on tiptoe or going around your subject as far as possible in both directions,
                  you may find wonderful angles you had never thought existed. When using a fixed-focal-length
                  lens, be light on your feet and approach your subject from a variety of angles. 
 Stopping Aperture Down to Keep
                  the Background in Focus 
 Using a fixed-focal-length lens
                  doesn’t mean you’re obliged to blur the backgrounds. You can also stop
                  aperture down to capture the background in photos that make it clear where the subjects
                  are and what they are doing. The lens may be fast, but blur caused by camera shake
                  is still a risk in hand-held photos taken with aperture stopped all the way down,
                  so choose an aperture of f/8 to f/11 or so.
               
Fast Lenses Shine Indoors 
                  
 Two of the benefits of fixed-focal-length lenses are that they keep blur
                  caused by camera shake to a minimum and are easy to use. A fast, wide-aperture lens
                  with a low f-number is a better choice for dark interiors than a zoom lens.
               
Choose a wide aperture for poorly lit interiors like that shown in the sample photograph.
                  Note, however, that because depth of field decreases as aperture increases, reducing
                  the depth of the area that appears to be in focus, you will need to keep your eye
                  to the viewfinder and focus carefully even when it is dark. 
 A fixed-focal-length
                  lens with a standard angle of view can of course create dramatic bokeh, but it can
                  also be stopped down to make it clear where the photo was taken. Another benefit is
                  that the angle of view is close to that of the human eye, making it easy to gauge
                  the distance to the subject. Fixed-focal-length lenses are also compact, so plan to
                  bring one with you on your next trip and take lots of photos rich in character.
