Photography Basics

The Process The Exposure - Camera and Lens Developing - Dark Room or PS… Printing – Darkroom or InkJet

The Exposure Camera Modes Auto, Manual, Shutter Priority, Aperture Priority ( A, M, Tv, Av,) What Makes an Exposure: Aperture, ISO, Shutter Speed

Aperture A value given to the size of the opening relative to the focal length.

Aperture Effects Wide Open Shallow Depth of Field Optical aberrations More Light Closed Down Large Depth of Field Diffraction Less Light

MTF CHARTS

Shutter Speed Focal Plane Shutter Slow speeds give more light Fast speeds less light 1/focal length

ISO Equivalent to Film Speed, grain size ISO from 50 or 100 upwards Low ISO- less sensitive to light low noise High ISO- more sensitive to light high noise

Focusing/Drive Servo/Single, Live view vs viewfinder Macro Focusing Autofocusing

The Exposure Goals: Set up Depth of Field, Shutter Speed, Exposure RAW FILES not JPEGS Focusing Manual vs Auto

Sensor Sensor Sizes: Medium Format, 35mm, Crop, Point and Shoot. Focal Length Conversions Advantages to crop/full frame

Histogram

Developing Misconceptions - Real Vs. Edited Capture One, PS, Elements, Lightroom, DXO Main Adjustments: White Balance, Exposure, HSL, Sharpening, Contrast What’s your end goal?

Online Postings Screens have low resolutions. CROP End Result

Printing Resolution depends on size, distance. More Megapixels, the larger the print. Printers at least 240 ppi, upsampling at most 10-15% Proofing / Brightness and Sharpening CMYK/RGB

Wildlife Photography Birds Macro Landscapes

Birds Special Equipment: Crop Sensor Better Telephoto Lens at least 200mm better range is mm Fast Shutter Speed, Wide Aperture Autofocus Monopod

Macro True Macro 1:1 Ways to shoot: 1:3 and Crop, Wide angle at close focus, macro lens, reverse lenses, extension tubes etc. More magnification- more light loss, less DOF Flash is very important/ Diffusor

Landscape HDR Tri Pod, remote control Wide Angle, Full frame advantage Hyperfocal length
