I will admit right up front that I have no idea why you’d want to over saturate a photo, but I bet there are uses for it. Also, I don’t really know what I’m talking about, but! I am capable of over saturating a photo. Check out these sweet flowers:

So here’s my guide to over saturating a photo:

• Get way too close to your target
• Make sure the flash is on and that it's bright
• Try to get the angle just right so as much of the flash as possible reflects directly back at the camera
• I bet you could leave the shutter open too long and that'd do it too.

I really should take a photography class. There are so many amazing photos on flickr, I could spend months and months just viewing cool photos.
