Gustavo was asking about how to take clearer pictures, so here's a short guide on what I do. I'm no master photographer, but this works for me.
A light background may reflect more light, but it'll also make the subject appear darker. In this case I'm using an off-white quilt.
I set the flash to not go off, as for me this always washes out the photo. Flash will freeze the action and allow a faster shutter speed, but these klickies aren't moving very fast, so I have no need for as fast shutter speed. I've set the white balance to indoor (tungsten) lighting. Leaving the camera set to daylight setting will result in a yellow tinge.
The camera is on macro mode, which on my make is indicated by the tulip over the middle button of the 3 along the top of the camera.
The camera is obviously on a small tripod (cost less than $10), and set to use the timer delay, to avoid shake. You could balance the camera on a box or book, but the tripod makes life easier. The timer is the stopwatch like symbol. Most cameras offer a 10 second delay timer. My fancier one offers a 2 second delay, which saves 8 seconds of the rest of my life each time I take a timer photo.
My camera is set 7" from the subject, on macro mode. Unfortunately Gustavo your Kodak Easyshare CX7300 camera doesn't seem to have a macro setting (I checked the specs and it says minimum focal length is 31.5 inches. )
To get the photo of the first camera on a tripod, I had to use a second camera on a tripod. Handheld wasn't good enough, I still got camera shake.
The third camera taking the picture of the second camera on a tripod taking the picture of the first camera on a tripod is on a tripod. At this point we ran out of tripods and cameras.
This is the picture the first camera took, unretouched. This is my customised SWAT tank, with rollbars added to beef it up and silver hubcaps replacing the standard yellow ones.
The bottom corner wheel is slightly out of focus, but the top of the top klicky's helmet is in focus. The depth of focus using macro mode is not great, maybe three inches at best.
Same picture, cropped and resized using Microsoft Office Picture Manager, which I think comes with most PCs as standard. There are fancier software programs out there, but this works fine for most of my klicky pictures.
You can see some dust particles on the vehicle and helmets, so I'm quite happy with this quality, but not the state of my dusting. The camera used is 6 megapixels, so I can zoom in more with the cropping and resizing and still not get grainy. It all looks pretty crisp to me except the klicky's left thumb, which I think is an oddity of the angle it's at to the camera.
