Depth-of-field

this is a good example of a photo having a narrow depth-of-field.

there are three (3) factors affecting depth of field:

- the diaphragm or aperture. in this photo, larger aperture (smaller number) was used in order to focus only a small part of the image.

- focal length. the smaller the focal length number of the lens, the greater the depth of field.

- distance to the subject. like in the photo, the closer you are to the subject,the smaller the DOF will be. while the farther you are from your subject, the greater the DOF will be.

light catch

i so much love light trails.
i did it once in my room and i really jumped out of amusement.
the thing there is to lower the shutter speed at the same time stabilize the camera (or use tripod)to prevent shaky shots, then do bracketing for the aperture to produce a really good result with vibrant lights.

the photo above is taken from an ordinary setting. the trail lights made the extraordinary out of it.
