I want to post my photos on the internet. How do I get a registered copyright over my images to avoid theft?
Despite cleaning my lens there is a weird black spot on my photos. What can I do?
Is there any way I can preserve and protect the quality of old prints?
What does maximum magnification ratio mean? I am confused.
The zoom feature on my cameraphone results in lower resolution photos. How do I avoid this low image quality?
What does DPI and PPI mean? Is there any difference between the two?
