Lesson 9

• Post processing is process of editing the data captured by camera while taking the photo to enhance the image
• Post processing can surely help in enhancing the image but not be able to convert a really bad exposure to excellent one. there are various stage of post processing.
• Workflow of post processing there are a lot of changes possible during post processing sequence of this changes is important as change made at one stage can affect the effectiveness of next stage.
• Some of the actions that are preferred after conversion to jpg files are:

  1. Red eye removal
  2. Local touch up of cloning to erase unwanted object in frame
  3. Adding of frame
  4. Mixing with other jpg files like changing the background.
• 10 tips for taking a great picture

  1. Get down on their level
  2. Use a plane background
  3. Use flash outdoors
  4. Move in close
  5. Take some vertical pictures
  6. Lock the focus
  7. Move it from the middle rule of thirds
  8. Know your flash range
  9. Watch the light
  10. Be a picture director
• Some of actions that may be preferred while editing raw file are:

  1. exposure value adjustment 2. white balance adjustment 3. Hue and tone adjustment 4. highlight and shadow recovery 5. vibrance and saturation adjustment 6. cropping and rotation
• Photography is a science, because there are

  basic principles of physics that govern success.
• Photography is art because its beauty is subjective.

• Three Basic Types of Photography

  1. Landscape
  2. Portrait
  3. Documentary
• Landscape is a photograph of the environment. It could be

  the forest, mountains, oceans, or your backyard.
• A portrait photograph is a picture of a person or animal

  that shows an emotional connection.
• Documentary photography tells a story without changing the facts. It

  can be a portrait or landscape.
• exposure is a measure of how bright a photo is as it saved to your memory card.
• Exposure is sometimes referred to as finished image.
• Aperture

  It is the size of the hole in the diaphragm

  that allows light into the camera.
• Aperture - Depth of field is an expression describing how much of

  a photo is in focus.
• Film Speed / ISO

  It measured in values using ISO numbers.
• ISO

  simply stands for International Organization of

  Standardization.
• LIGHTING

  One of the skills that separates photographers from snap shooters is the

  ability to solve lighting problems.
• ▪There are two primary factors to consider for light: Direction and Colour.
• colour of light is measured by temperature in Kelvin (° K).
• ▪The amount of light that strikes the film/chip is measured in stop and is also known as exposure value
• ISO - the light sensitivity of either the film or imaging sensor.
• SHUTTER SPEED

  to admit light into the camera, and onto the digital

  media or film for a specific length of time.
• Faster shutter speeds mean less light on the image sensor. Slower shutter speeds mean more light.
• STAGES OF POST PROCESSING

  1. Fine tuning of RAW file
  2. Converting RAW file to easily readable formats like jpg/png/tiff
  3. Editing of jpg to remove unwanted features
  4. Mixing of various files to achieve creative result.
