get more megapixels

I was looking at your website and book and had a question: Is there any way to hack a digital to increase the megapixels? I have an Olympus C-2100 Ultra Zoom which cost $700 new and has a great lens, etc. However it only has 2.1 megapixels. Is there a way to hack into it and get it up to 6, 7 or 8 megapixels?

Thanks,

It's unlikely to increase the megapixels of your 2.1 megapixel camera, without using digital interpolation (digital zoom). In all of the digital camera today, the firmware has already maxed out the capability of the sensor. In your case, the Olympus C-2100 Ultra Zoom has a 2.1 megapixel physical sensor.

One thing you can do to increase the size your image without doing a "digital zoom" is to take four separate picture of the entire scene, in a grid-like manner (like in the children game four-square). Make sure to only overlap slightly from picture to picture. Then use a image "stitching" software to combine the four pictures. You will have effectively quaduple (minus the overlap) the image data (8 MP on your Olympus C-2100 Ultra Zoom).

Thanks for the tip, I'll try it out. I have done some side-by-side stitching of 2-4 photos to create a panorama in Adobe Photoshop Elements. But one problem is that the automatic exposure setting on the camera ends up exposing each picture slightly different. Maybe I should try using the manual exposure setting.
