What I Learned About Camera Exposures

In order to get good pictures you need to know how to use a few things. You need to know how to use ISO, Aperture, and Shutter Speed. The shutter speed controls the exposure. The exposure shows how light or dark the pictures come out. The aperture how much light is let into the camera.

File Formats

  • PSD (Photoshop Document) needed for extensive handing of original photos ex. retouching
  • JPEG (Joint Photographic Experts Group) photos that are for personal use, small prints, and social media
  • BMP (Bitmap Image File) large files, each pixel has saved color data without compression
  • TIFF (Tagged Image File Format) uncompressed files, allows to have extensive post-processing
  • GIF (Graphic Interchange Format) used to post to the internet, Image quality is not sacrificed due to lossless compression, ability to maintain the transparency
  • RAW highest quality files is what you want and raw offers just that, professional photographers prefer this.
  • PNG (Portable Network Graphics)  compressed in lossless format, retain all details, small size file so that they can load faster on the internet
  • DNG (Digital Negative Format) used as a main raw file, also as an alternative for native raw format

Camera Modes

Portrait Mode is used when you are taking a photo of a single object. You need to get close to your object so that it focus on it.

Manual Mode is used by mostly anyone who owns a camera uses this mode. It is the easiest mode to work with.

Landscape Mode is used to capture points of interest. The photos are taken at a wide angles,  from a distance.

Automatic Mode it pretty much does everything for you. Your camera chooses your ISO, it selects your shutter speed, aperture, and focus for you.

Night Mode is to shoot when their is low light. It captures detail in the background and uses a longer shutter speed.
