19. 19 Digital Cameras

20. 20 Choosing a Digital Camera  Easy to use and/or many controllable features Point and shoot versus a lot of control?  Optical zoom of at least 3 to 1 Digital zoom is less useful and decreases the resolution  Strong macro capability Test it in the store  Size and price

21. 21 Megapixels  Megapixels are calculated by multiplying the horizontal and vertical pixel dimensions:  1600 x 1200= 1,920,000= 1.9 MP  Only need a resolution of 1024 by 768 pixels (not even 1 megapixel) to fill a high quality computer monitor or a PowerPoint slide

22. 22 2400 x 1800 = 4.3 mp Resolution and megapixels 1600 x 1200 = 1.9 mp 640 x 480 =.3 mp

23. 23 Compression  Compression allows for smaller size files with less information but equal pixel numbers  TIFF – no compression, used for print publishing  JPEG (Joint Photographics Experts Group) Fine 1:4 compression Normal 1:8 compression Basic 1:16 compression

24. 24 Printing Photographs  Highest quality print will have the highest number of pixels and the lowest compression  A 1600 x 1200 when printed at 300 dpi makes a 5.3 x 4 inch print  At 150 dpi you can print an 8 x 10 photo  dpi are like peanut butter – the more you spread the dots, the thinner the peanut butter
