Photography DSLR and Lens PowerPoint read and write  

 

The 25 facts and details that I have learned from the powerpoint: 

 

1. DSLR contains mirror to view accurate image about to be captured 

1. DSLRs are digital cameras meant to resemble 35mm film reel cameras 

1. DSLRs, compare to phones and point shoot cameras, have detachable lenses allowing more flexibility 

1. A lens already with the camera is called a “kit lens” 

1. A higher number of focal lengths means further zoom capabilities. 

1. A fisheye lens has a focal length as low as 4mm! 

1. Portraits use more telephoto focal lengths around 100mm 

1. Exposure is a balance of 3 separate settings- aperture, shutter speed, and ISO 

1. ISO is the sensor’s sensitivity to light 

1. Lower ISO = less grain 

1. Higher shutter speed for fast action shots 

1. Shutter speed should typically be 2x the video frame rate 

1. Use tripods for more stable shots 

1. Smaller number means LARGER aperture! 

1. Fast lenses go up to bigger aperture settings. 

1. Larger aperture means shallower depth of field 

1. Shutter speed causes/effects photo blur 

1. ISO effects the amount of grain 

1. Aperture effects the depth of field 

1. White balance adjusts color balance of photos 

1. White balance varies from the subject, ex- candle will be warmer, sky- cooler 

1. There are warm and cool aka redish orangish to blueish white balances. 

1. Full auto mode on camera does everything for you 

1. Manual mode lets you choose everything 

1. AV mode allows you to choose aperture, while camera chooses appropriate shutter speed.
