Re: true base resolution for BH-725
All the listings on ebay falsly claim of having "4x Optical" zoom. But when i went to Bell & Howells website it states of having "4x DIGITAL" zoom.(http://www.thpsales.com/store/viewItem.asp?idProduct=1029) So, who are you going to believe? Somebody just trying to make money off ebay? Or the manufacturer?

Important information would be what screen you have, and what resolution you are running that screen at.
There is no optical focus happening in an LCD computer screen, however the clarity of the screen can be affected by a mismatch between the resolution of video signal the computer is sending, vs, the resolutions that the monitor can handle.
In Windows 10, check under Windows Settings, System, Display
You will see the Scale and Layout, and the Resolution. Ideally, you would run at 100% for scale and at the native resolution of the monitor, whatever that is for the particular monitor.
Changing the scale and resolution to non-native settings in some cases causes the video signal to be interpolated which can lower quality.
This camera takes a lithium battery and if it is left to fully discharge then you may never be able to charge it up again. Your answer may be another battery. Find a cheap third party battery to try it out.
1. Digital zoom is a part of digital cameras, and camcorders, which helps to crop the entire image, and then digitally enlarge the size of the viewfinder of the portion that is needed to zoom in on
2. Digital zoom crops the image down to a centred area with the same ratio
as the original, and also interpolating the result back up to the pixel
dimensions of the original. this method involves cropping, hence the
resolution and quality is reduced
3. Digital zoom, crops a portion of the image and then enlarges it back to size. And due to this, image quality is reduced in comparison with the original one.
4. Using the digital zoom allows the user to get closer to the subject when the photographer wants to be discreet about taking pictures, like taking a picture of a person in a graduation ceremony.
1. While taking a picture using a Camera to want to get a close shot of the subjectwithout moving physically closer, photographers use the optical zoom.
2. The optical zoom ratio of a digital camera measures how much the lens can actually zoom in to make subjects appear closer. Optical zoom, enlarges a picture while keeping the resolution and sharpness of the picture high.
3. There is no relation between optical zoom and the resolution of the photo, as optical zoom only enlarges the whole image or the subject to a certain range. So image quality only depends upon the mega pixel (MP) of the camera
4. Optical zoom is very useful, while taking a picture of a landscape, or to get a closer view of a subject, without reducing the quality of the entire image, like taking a picture of a Rainbow in the sky.

I have downloaded the driver softer for you and kept on below mentioned link for you. You just need to copy and paste the below mentioned link on internet explorer and click on it. Once the link is open than you just need to download the file which is available on the link. Save the file on your computer and from that file you can install the driver. Link is mentioned below: http://www.transferbigfiles.com/9e0886d7-f703-4e78-82b3-a9c7990ac0c9?rid=Y36SEDW2FqAwYCzqjCk7Og%3d%3d
Yes you do this from the application that yu are using to do the scan. Chooese the setup or preferences tab for the scanner in the app and you should get a list of available optical resolutions from 75dpi, 100 dpi, 200dpi, 300dpi, 600dpi, 1200dpi upwards.
The optical resolution is 1200 x 2400dpi max and interpolated (from software) is 19200 x 19200 dpi.
increase in dpi will not increase the resolution.
dpi = dots per inch
for example you have a res of 1024x768
at 72dpi you get a printed image of 14.2x10.6 inch
at 300dpi you get a printed image of 3.4x2.5 inch
only thing possible is to interpolate the image. but thats **** in my opinion.
I think you stumbled onto a tough problem. I did a little research on Google and it looks like Bell and Howell was split up and various companies picked up the pieces.
I think Kodak got the camera division in 2001 (but I'm not sure). If they did you might try contacting their support dept.
It's important to understand this difference, as you could be disappointed with the results if you use one rather than the other.
Optical zoom works like the zoom on a traditional film camera. When you push the button to zoom in or out, physical lens elements move inside the camera, reducing the field of view and making the object you're shooting appear closer.
Digital zoom, on the other hand, has no moving parts. The camera interpolates a small portion of an image to artificially restore the file to its original size. Using its electronic brain, the digital camera analyzes what it sees and digitally zooms in, usually two or three times closer.
Unfortunately, digital zoom also reduces the resolution of an image, so your picture will tend to be more pixilated than the same image taken with an optical zoom camera. If you're just snapping an image to e-mail to a friend, this loss of resolution won't be so noticeable. But in situations where the highest quality counts, skip the digital zoom and use your PC's image-editing tools to zero in on your subject.
