Marco Photography- Close Up
Filters are an alternative to a macro lens
You can get as close as 3″-6″
(You can experiment on digital cameras using the macro feature designated with a tulip symbol)
Filters sets are usually +1, +2, +4, Macro
The bigger the number, the greater the magnification and the closer you can get to the subject.
REMEMBER: you must attain focus (it will be difficult), But, not everything may be in focus
