Question about Canon PowerShot A640 Digital Camera

1 Answer

Low resolution on highest setting

I have been using my canon powershot a640 for about a year now, i always keep it on manual, large, superfine. i use macro, shoot jewelry and use a lightbox. in the last month my images have become very grainy, as though i were on an extremely low setting. i have double checked everything, the settings are still the highest...is there something else i can do or does the camera need to go back to the company? the pictures i was used to were wonderful and clear!
thank you in advance for your help!

    A focusing problem perhaps? Mine seems to have an intermittent fault in this area. Sometimes it will not autofocus and the resultant picture is...well, out of focus!

    the camera sometimes takes good pics but most of the time takes blurry and grainy pics, regardless of the mode its in. what kind of fix or repair does my unit need? it just irritates me that a 10MP camera doesn't perform to its full potential. i've seen other cameras with 5mp's take better pics than this one. hopefully this is a fixable problem

Did you check the ISO setting - a high number there would possibly make the pictures grainy.
Hope that helps.

Can't get a 2MB image. What am I doing Wrong?


Jpg images use a form of compression. If the camera sees an area that is all white for instance, it knows that that one white pixel is the same as those around it and doesn't need all the information. This reduces the size. If you have highest res and superfine compression the only other thing you can is increase physical size if the camera has that choice, or buy a Canon Rebel or Nikon D90 :>)

Remove time date picture


Try to use menu and settings. Also, date stamp can be used only in very low resolution images, change your image resolution and quality back to this large/superfine setting. And you can find the information related to date stamp in user guides. Look for them here Canon Camera user guides and owners manual

I take pictures with this camera that I blow up to 20" X 30" or larger(ecellent by the way). Can not remember how to set the camera for this. It is now set at normal.


Press the FUNC button. Use up/down to select the desired resolution (you probably want Large) and left/right to select the desired compression (you probably want Superfine). Press the SET button to confirm and save your changes.

This is on page 40 of my copy of the manual.

Resolution


The XTi allow to set different image size for manual modes an for AUTO modes. So you can set a Large size superfine for auto and RAW type for manual modes. So check the size settings under manual and automatic modes.

However, the "smal" resolution (1936x1288 px) on XTi will allow you to print good 5x7 photos.

Grainy pictures


You have likely set the camera to shoot photos in low resolution, or high ISO or both. Check your camera manual for detailed instructions on how to set these options.

If you don't have your computer manual, you can download one from this page at Canon.com. This is for the Powershot S500, this is the same camera as your IXUS 500, they just gave it a different name in different countries.

Always set the camera to shoot in the highest quality resolution mode. Memory cards are relatively cheap and you don't want to end up getting that photo of the lifetime but because you shot it in a low resolution mode you can't get a good print!

If you are shooting in low light the camera may be automatically boosting the ISO. There are only 3 ways to shoot in low light:

1) Flash - only works when your subject is relatively close to the camera.
2) Increase the ISO which results in noise in the dark areas of the image.
3) Use a tripod and a long shutter (slow shutter speed).

I own a canon Power Shot SD110, and no longer have the manual. I want know how to set the mega pix to have highest resolution possible. Can you tell me how to do this?


To get the best resolution, you need to set it to Large, Superfine. When you look at the LCD, in the lower left corner you should see an "L", and right above it a quarter circle with an "S" in it. If it shows anything else, press the Func button, use the down arrow until you reach the compression or resolution, then use the left/right arrow to select what you want. Press the Function button again to save the setting.

You can view/download a manual for your camera here.

How do I adjust the resolution that the photos are saved?


To change the resolution and compression:

1. Press the Func button.
2. Scroll down, if necessary, to the icon in the lower left corner of the LCD.
3. Use the right or left arrows to select L (large), M1, M2 (medium), or S (small). Press the Set button.
4. Use the right or left arrows to select superfine (quadrant with S), fine (quadrant), or normal (stairsteps). Press the Set button.
5. Press the Func button to exit.

Large/superfine images will take up the most space on the memory card. Small/normal images will take the least, but the picture quality will be less if you're printing the pictures.

There is a table at this link (scroll down) to show you how many images will fit on a memory card at different settings.

Need higher resolution by tomorrow


For the best resolution, use your FUNC button at the back of your camera. Scroll down on the left hand side to the bottom of the menu which starts with AWB, Set your size of image to 3264x2448 and then using the SET button, select S, which is superfine

Camera takes a few low resolution pictures even when the settings are for high res pictures


You should take your camera to service.

Normal cameras are meant to work above 0 deg C (32 deg F), but usually they work even at -15 C (5 F). When you work below the freeze point there may some anomalies, usually LCD turns blue or purple but photos look OK on a computer. Sometimes the camera refuses to take photos or shows bad focus, lens zoom mechanics get stuck etc. And you always experience significantly shorter battery life when in the cold.

It's a good idea to keep the camera in a warm bag and take it out before shooting. You can also keep it under your coat if you're not practicing a sport like skiing (because of body moisture).
