Some People asked me to make some designs for their store frontpage.
I know the illustration programs is the best to keep the resolution hight.
But the frontpage contains pictures like food & drinks and because of this I am afraid to lose the quality because the size is 4M * 4M.
I've edited the pictures in Photoshop using real sizes and 300 ppi, but the file size is bigger than 2GB.
What do I have to do to make the file size smaller yet keep the quality.
Another question; the frontpage contains windows. I have to cut one picture according to these windows. Is there any other software instead of Photoshop or Illustrator to cut and distribute the pictures according to the frontpage windows?
