G. -- dare I ask where the rest of the spider is...?

I've seen some websites with scanned images (Thanks, Doug, for showing me that Cat Scan is still alive and well - hadn't seen it in a few years) but never motivated myself to experiment (Deb -- I like your thoughts about "not moving too far from the chair" )

You folks have tapped into the resources of another potentially useful tool -- it'll be fun to see what you come up with next.

CJ - The rest of the spider is still there! I was cleaning out a closet when I found the poor dead spider. I tried to scan a living one, but it proved to be impossible as it would not stop moving. This one had been dead for some time....everyone who hates bugs has run screaming from this thread!

Lisa - That's a nice photo. You need to go find a spider to model for your new camera! I have a close-up lens for my old Canon AE1, but never had much luck with it due to the very limited depth of field.

Greg - that looks like some of the well-preserved spiders I find in my closets.

I tried scanning my spider but it didn't work too well. I ended up having to take his/her picture with an Epson PC 700 digital camera on macro about 4 inches away. Luckily it was a very cooperative subject.

What ever he want's, he's not my pet. Actually the only way I would get that close to something that big and hairy is if it were dead already. He's encased in a resin globe. That's why the scanner didn't work so well. Every light source reflects off it. I actually was surprised at the detail I was able to get. It's an older Epson digital and I used the built in flash. All I had to do was clone out one small flash point on the stones.

YO Greg

"Enough Spiders Already"

I have been giving your scanning technique some thought and tried it. I don't have a great scanner but it will scan up to 2400 dpi resolution. It is a canon canoscan 1240u. One of those scanners that is only 1" thick.

This is what I tried.

- I plucked a tail feather from my pet Bubba's tail (just kidding he gives them to me by the bunch)

- I put the feather under a printer paper box. Approx 3/4" tall.

- I cropped and scanned at 1200 resolution.

- The results are not terrible, but I noticed that if any part of the item is off the glass, it is out of focus. You don't seem to have that problem.

- I also tried a watch.. Same results.

Questions:

Do you clean up noise and artifacs. I seem to have a lot.

Is there a way to increase the depth of field??

Is there a better way to do this. Is the box the right size?

Here is a dumb one. How do you clean your scanner glass. I'm curious if there is a better way.

I am attaching my results, I reduced the resolution to 150 dpi.

Thanks for the help
Interesting thread

Jerry

Jerry, I think your Canoscan uses CIS (Contact Image Sensor) technology, which does not give any depth of field when scanning. (Other scanners use CCD (Charged-Couple Device) technology - which does give some depth of field.) I don't think there is any way to increase the DOF for CIS-type scanners.

Thanks Jeaniesa

I figured it was something like that. CIS vs. CCD technology is not something that I would have investigated when I was scanner shopping. I'll just have to look at the impressive scans that Greg and the others can produce.
