Question about Canon PowerShot A710 IS Digital Camera

Fishbowl effect in my image

Hi, I am trying to take pictures of old documents. The librarians recommend this as a safer alternative to scanning or xeroxing them. When I do so with my Canon A710, though, I get a fishbowl effect. The middle of the image is bowed out and the tops and bottoms are pulled in. I am seeking a faithful, square, reproduction. I've been unsuccessful with the users manual when trying to change a setting or fix the set up.

Any ideas?

Consider moving the camera further from the document, and then using the zoom (with a tripod) to close in on the document. You may also need to use a "book holder" with this technique. The A710 also has many manual features that you can tweek. Consider using manual focus to ensure sharpness in the image of the document. Also try varying Shutter and Aperture priority (Tv and Av) settings. Recommend first doing this at home to find what works best before going to the library.

Try setting it to a slower effective ISO rating, this may improve both situations. An ISO of 100 is effectively a slower picture speed, but it increases the pixel density so your pictures should appear better.

If you did not get a manual, I do suggest it because there is a great deal that camera can do that is not always apparent from the buttons you see.

If you need to download one,
pick your model or family of camera and when that page has loaded you can download a number of documents.

How do you upload pictures from the Casio Camera onto the computer/laptop

Skip the computer drivers, software, and so on.
Get a card reader/writer and take the card out put it in the card reader and download your files to where you want them on the computer.
In Windows, I recommend to always make a root folder outside of Windows. By doing this, you may save your files from your camera should the computer crash for any reason. The files in the separate folder named anything such as "my Casio pictures", or what ever you want.
This is much safer, rather than in My Documents folder. That is because if the system has to be restored (on most Windows before Win7), then you loose all files in those MY DOCUMENTS folders.
On Linux or Mac, it it also safer to make a special folder where you know they are.
Hope it works okay.

Hi, you can edit your Digital images with many Image Editors available today.

My personal suggestion is to use the freely available alternative to the Photoshop Software called GIMP which is short for Graphical Image Manipulation Program.

Lens is blurred when you aim to shot


This is a common problem with these camera's. This is either faulty screen or a problem with CCD sensor.In both situations,repair is never recommended as buying a new camera would be cost effective as compared to getting this camera repaired. Try to look at previously saved video's or images, if you still see blurred lines, it would confirm faulty screen unless if the saved video's or images are fine, and this happens only when you try to click a picture, this would confirm faulty CCD sensor.

I wish i could have a better solution.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

When trying to take pictures this apears on the sceen. !AF

My Fuji E550 manual says this icon indicates the autofocus cannot work effectively under the present conditions. If your image is too dark move to a distance of around 2m (6.6 ft) from the subject. Alternatively use AF lock to take the picture.
My thought -- might try taking the shot even if dark and lightening it extensively in a post production program like Picasa. I never discard a dark shot until I've tried this -- with many good results.

My pictures were deleted from my memory card i want to undelete them

Do it as follows, I am sure you can undelete your photos easily.

First things first: DO NOT take any more pictures or videos to the camera that you want to recover files from in case you may quite possibly ruin your chances of photo recovery.

Then connect the device to your computer and have a try of Digital Photo Recovery, a program which can recover pictures, videos can music files deleted or lost easily. If you are running a machine with Mac OS X, go to Photo Recovery for Mac

You should remember - the more you use your the device, the less likely you may be able to recover the images back! So STOP using it as soon as possible. Best regards and good luck!

Insignia digital photo frame won't recognize some .jpgs

When you save in Photoshop make sure you select "Baseline ("Standard") on the JPEG options when you save. That should fix the problem for you. It did the trick for My Kodak SV710 digital frame which wasn't displaying images I had edited in photoshop.
