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?

Change to resolution after picture taken


Sorry, can't be done. Those pixels weren't recorded, so there's no way to regenerate them.

Think of it this way. Suppose you look out the window and see a red car drive by. Look out the window an hour later and maybe a blue car drives by. Now, how many white cars drove by between those two cars? If you weren't looking (or had a surveillance camera), there's no way to tell. In your picture you've got a red pixel over here and a blue pixel over there. There's no way to tell what was in between.

There are some tricks that can be done to interpolate. If you have a bright red pixel and next to it a dark red pixel, then the pixel between them probably was a medium red. But maybe not: there could have been a blue object in between. Or the pixel in the middle might have been the same color as one of its neighbors. There's just no way to be certain.

What is the difference in the optical and digital zoom?


Hi,

Find the difference below

Digital Zoom

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.

Optical Zoom

1. While taking a picture using a Camera to want to get a close shot of the subject without 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.

Ron

The svp hddv-2200 is listed some place on the web as a 12 mega pixel and other places as 5 MP. SVP says that it comes with 5 MP sensor but a 12MP resolution. Is this as marketing gimmick? If not could you...


Usually this is described as the higher figure "by interpolation". Sounds like they average two or three sensor spots in software to interpolate one in between or something like that. Yes, it is a marketing gimmick, but not an out-and-out lie. If you compare like with like (sensor Mps with sensor Mps) you will get a better sense of what the price should be.

I need a driver for installation on my pc


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:

Want Increase resolution from 72dpi to 200 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.

Does Hypict really help the resolution?


Hypict degrades image qulity a bit because it is interpolation. You can basically do the same thing in photoshop with similar results, I haven't tested this yet. What it does do is make a beter looking 11x14 print than using the 1200x1600 setting, with no after shot manipulation by the user, so if you knew you wanted the image bigger for some reason, and didn't want to manipulate it later you would do this.

Software and/or driver for BH725


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.

Optical vs. digital zoom


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.
