| isnt working in a church an amazing job? My wife is the daughter of a pastor and I am the son of a deacon. I must say people in church do a better job of driving people away than the devil ever could (not asking for a theological debate FYI). What was it the Gandi said ... something like "I would be a christian if chrristians were like christ"...
anyway
taking a 100dpi image and bumping it up to 300dpi will downgrade the image usually/always. This is because the computer is trying to add dots that dont exist, thus its guessing. If the images are not of great quality to start with it will be greatly amplified by bumping up dpi. Working with poor photos is an amazing pain! My dad tried to put together a picture book directory in our old church, it didnt go well. I commend you for all your work however |
