Problems
41.- Think you want to print out a photograph with a size of DIN A4: 210 × 297 mm maintaining a printing quality of 200 dpi. Which resolution would the image need?
210 mm / 25.4 = 8.27 in
297 mm/25.4≈11.69 in
Step 2: Multiply by the desired dpi (200 dpi)
Width in pixels: 8.27×200≈1654 px
Height in pixels: 11.69×200≈2338 px
42.- Which resolution would the same picture need to have a 300 dpi picture?
Width: 8.27 in
Height: 11.69 in
Width in pixels: 8.27×300≈2481 px
Height in pixels: 11.69×300≈3507 px
Required resolution at 300 dpi: 2481 × 3507 pixels
