#5 The Golden Rectangle - 8 Effects Every Photographer Should Know About | via StumbleUpon

8 Effects Every Photographer Should Know About - StumbleUpon:

I've heard of some of these basic photographic tools of composition, even using a technique like the rule of thirds intuitively. But who's heard the word Bokeh? (and where have I been?) That's one of the techniques that you use without knowing the name. It sounds like an ancient deity or spirit guide.

8. Contre-jour - straight into the heart of the sun
7. Long Exposure
6. Fill Flash - my photography improved a lot after learning how to use this setting on a point-and-shoot camera. This reminds me of another interesting photography word - the gobo.
5. Golden Rectangle - natural patterns have a subtle and compelling way of grabbing your attention.
4. The Golden Hour - In the badlands of South Dakota or canyon walls of Manhattan, these are the best times of day.
3. Rule of Thirds - symmetrical asymmetry
2. Panning - They're off and running. Often seen the effect but never knew what I was looking at. Actually, I mistook it for bokeh. Cool, Something new to try.
1. Bokeh - depth of field makes the background of the image out of focus.  and the subject in focus

Take photos for HDR images

Keep the following tips in mind when you take photos to be combined with the Photoshop Merge To HDR command:
  • Secure the camera to a tripod.
  • Take enough photos to cover the full dynamic range of the scene. You can try taking at least five to seven photos, but you might need to take more exposures depending on the dynamic range of the scene. The minimum number of photos should be three.
  • Vary the shutter speed to create different exposures. Changing the aperture changes the depth of field in each exposure and can produce lower-quality results. Changing the ISO or aperture may also cause noise or vignetting in the image.
  • In general, don’t use your camera’s auto-bracket feature, because the exposure changes are usually too small.
  • The exposure differences between the photos should be one or two EV (exposure value) steps apart (equivalent to about one or two f‑stops apart).
  • Don’t vary the lighting; for instance, don’t use a flash in one exposure but not the next.
  • Make sure that nothing is moving in the scene. Exposure Merge works only with differently exposed images of the identical scene.
