Pictures and scans

mansco

I have been trying to scan my coins and they all come out samll with low resolution. The instructions I have don't seem to help. What have forum members done to get good quality scans of their coins?

Any help would be appreciated.

You can set the resolution of the scan.

On my software when I choose "scan a photo" up pops a dialog box. There is a button I can press that is labeled "adjust image quality". When I press that I get another dialog box that has a place were I can "adjust resolution". This was 72 DPI when I first looked at it. Try making it 300 DPI (Dots Per Inch).

You software probably has something similar.

Carl,

What software and scanner do you use?

The bad thing about scanners is they occasionally give a pink or green reflection on your coins.

Is there a way with your scanner to prescan - expand on certain areas - change format (B&W/color photo/ color drawing)?

I do not know of any scanner that does a decent job on toned coins.

I purchased a HP scanjet 4400c. This replaced an older UMAX scanner I had that wouldn't work with my computer.

I use Adobe PhotoDeluxe Home Edition to trim and size my images. When I ask PD to scan an image it brings up a dialog box that I believe came with the HP. I was using PD with my old scanner and the UMAX had a similar dialog that allowed the same adjustments.

I now mostly use a digital camera. It is harder and takes more time. I still use PD to crop the images.

For toned and deep cameo coins it sometimes helps to put something under the edge of the slab. This tilts the coin and that seems to help.

Dump the Scanner and get a Camera.



Some people say that direct Sunlight on the coin gives them thier best pictures. Its just the opposite for myself. The Darker the room the better with just a single light source. Late Night or early morning works best here.

I have a digital camera, but don't seem to be able to get close enough for a focused picture. I have an Olympus with 2 megs which should be big enough. I'll try that again, but scanning would seem to be easier.

The Digital Camera idea is a really good idea! Make sure you get a good tripod to go with it. I have some money invested in my coins so, I purchased a Pixel Link digital camera to record my coins. I don't recommend this if you're not going to use it a lot (make it worth the money!). I got tired of my scanner and the difficulties that go with it mainly the dark copper coins!

I've scanned a few coins using a Visioneer One Touch scanner. It gives me options ranging from 200 dpi to 2400 dpi, and the files that it produces are huge, sometimes over 30 mb. I then export them as JPEG files, crop and resize, and can reduce them down to less than 100 kb. The scanner gives excellent detail, but the color and luster are usually not very true to life, so I prefer the digital camera.
