Any help on this pic ?

What can I do to make this pic sharper? I'm using a Mavica fm 85, close up setting. I have built a 3 sided box that's got a florescent light above, 60 watt bulb lamps on either side and everything white inside the box. I rest the camera on some books when I click. Any ideas ? Thanks, Steve in so az
 
I could improve it slightly in PhotoShop but it still looks poor. With that Mavica you should get a fantastically crisp picture.
Actually it looks like you have too much light ... it appears washed out as there is not enough contrast. Usually you try for an asymetrical lighting scheme with one side being brighter to provide some contrast. Also you shouldn't mix light sources which are so different in color.
Another thing I noticed was it is only a 6k file. Knowing what a good quality picture is from the Mavica I'd say you over-compressed it which will give a very poor quality (Use medium - or higher - rather than low for compression if image quality is important). A picture size of 20 to 50k at 72 dpi would be reasonable for viewing on the web and would look an awful lot better.
Hope this helps some.

Gord - With the compressing , are you referring to the image size ? I have it at 1280 ( 3:2 ), I can go to 1280 X 960, or 1024 X 768 , or 640 X480. Thanks for any help as I know very little here. Also, I did take the object out into the shade and made a much better pic. I assumed the more light the better, but I guess not so. Thanks, Steve in so az
 
Steve,
Glad to see you got an improvement.
This can be a difficult subject to explain in writing but easy to show in person 8^P. If you have the right image processing program it can be pretty easy to do.
I wasn't talking about the "640 x 480" type of figures that you mentioned. That refers to the image size in pixel (if your picture resolution is at 72 dpi which is standard for a monitor your image would be 640/72=8.3 inches by 480/72=6.7 inches which is a good size on the average monitor for a picture of coins). Normally you don't need bigger sizes than that so if your pictures are larger you can resize them downward and the file size will be much less.
Regarding compression ... I was referring to jpeg compression. When you save in jpeg (which was what your pic was) there is usually an option which asks what image quality you want. Some programs use high to low quantity while others use numbers (ie 1 to 100 with 15 being low quality, 30 being medium, 60 being high, etc.). Usually for a good picture on a monitor a medium or lower will give you the smallest file size with little noticeable degradation in image.
Keep experimenting as that is the best way to come up with a method that works for you.
Hope you recover a lot of finds worth taking pictures of ;^)!

My digital has a fit if you try anything but the farthest zoom to use either macro setting. No zooming. (C2500L Olympus). Also try using afternoon sunlight such as the BBQ pit. Rick Martin told me of that trick and it's the best...
I know you're doing something wrong.
Good hunting... Guvner..
