12 Image Path in a Digital Camera Sensor Camera Processor raw format raw file (usually a jpeg) Memory Card Computer Keep your raw files!

Memory Card - what stores the images in the camera 1 bit = 1 on/off switch SD Card 8 bits = 1 byte 1000 bytes (approx) = 1 kilobyte 1000 kilobytes = 1 megabyte The bigger (in megabytes) the card, the

13 Memory Card - what stores the images in the camera 1 bit = 1 on/off switch SD Card 8 bits = 1 byte 1000 bytes (approx) = 1 kilobyte 1000 kilobytes = 1 megabyte The bigger (in megabytes) the card, the more images can be stored before erasing it megabytes = 1 gigabyte 1000 gigabytes = 1 terabyte... but you can use megabyte as your point of reference 4 meg card = your grandmother s you can retrieve erased photos (sort of) cards are reusable until they are not meg card = probably usable 256 meg card = pretty good 1 gig card = very good 8 gig & up = certainly more than you need

15 Downloading (uploading?) card reader USB to camera SD card slot in computer Image Capture (in applications folder) Make sure you know where your images are going! Eject your memory card! or else

16 The first three imperatives Get close to the subject and move around Don t center the subject unless that is best Look at the light - that is what you are photographing

20 Opening Raw files in Photoshop Saving in Photoshop format

21 Pixels (Picture Elements) each pixel can be any color but only be one color

22 Sizing images for screen or print You must have enough pixels so that they will be small enough to not be visible (for either screen or print). Our eyes can see smaller pixels in a print.

23 Sizing Images for Your First Assignment Will the pixels fit into a 1000 x 750 box for your assignment?

Sizing prints for email or web (screen) Whatever number

24 Sizing prints for or web (screen) Whatever number of pixels gives you the right size at 100% in Photoshop.

25 Histogram

26 Levels Adjustment (fit image in window) before levels adjustment 1) dragging highlight slider to right side of mountain 2) dragging shadows slider to left side of mountain 3) dragging gamma slider to make the image better 4) readjust highlight and shadow sliders to make the image look better

28 Controlling the View normal view tab key to hide palettes f key to cycle window modes f key to cycle window modes

Saving as Photoshop or JPEG file? Photoshop (.psd) No loss of quality (lossless) Can save layers, selections, etc. JPEG (.jpg) Lossy (depending on setting) Cannot save layers, selections, etc.

29 Saving as Photoshop or JPEG file? Photoshop (.psd) No loss of quality (lossless) Can save layers, selections, etc. JPEG (.jpg) Lossy (depending on setting) Cannot save layers, selections, etc. Bigger file size Cannot put in any application Smaller file size Can put in (just about) any application JPEG for transmitting or storing finished photo (whenever size is a premium). Photoshop for working files. Extension is important. Don t change it!

30 JPEG Quality Image quality versus Image file size

43 Grayscale Mode Grayscale = 8 bits (2x2x2x2x2x2x2x2=256) Each pixel can be one of 256 levels of grey

called 24 bit) Each pixel can be one of millions of different colors (2x 2x

44 RGB Mode RGB = Red, Green, and Blue 1 greyscale channel for each color Each pixel can be 256 levels of each color (R,G,&B) 3 x 8 bit (or more commonly called 24 bit) Each pixel can be one of millions of different colors (2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x 2x = uhh..millions)
