Document Summary

To nders and he difference be ween des r c ive and non-des r c ive image edi ing. To learn some of he more common ools in pho oshop o manip la e images. To nders and image resampling (in erpola ion) and how i affec s he final image. Image resol ion is very impor an o consider when combining images! 2 pixels for every prin ing do (150 lpi = 300 ppi) Dimensions sho ld be hose req ired for he final placed image size. Therefore, a 4x5 image a 300 dpi wo ld have a o al of 1 800 000 pixels (4x300x5x300) Resol ion of a 4x5 300 dpi image falls o 150 ppi when dimensions are changed o 8x10. Pixels are cloned when dimensions are increased, and he ppi s ays a 300. They m s be a he same resol ion.
