Question about Digital Cameras

1 Answer

Image Properties shown....You've been great!!!! Few more....


1. Any advantage to mess with the digital zoom?
2. The Image Properties on all 3 pictures show the Exposure Bias as 0.0 and the shutter speed was 1/60 on all 3.
3. So it would be safe to assume that someone else took the pictures with these settings & the "Self-Timer" wasn't used?
4. To confirm, 4.6 and the 9.11 is distance in feet if not using auto-focus?

1: it just adds and copies existing pixels with the digi zoom. I never fooled with it for you can just take the image with a paint program and blow it up as big as you want.. with decreasing detail.just start with a nice high megapixel like 5M camera but you'll need a bigger memory card.

2: exposure bias at 0.0 is what the camera sets as standard. adjusting this in the "M" mode allows more exposure "+" or less "-". making the aperture bigger or smaller to allow more light or less at higher shutter speeds or low speeds. 1/100 is good.
3: yes but try it out and put it on automatic first.
4: focal length or f stop I'm confused. The aperture setting is known as the f-stop. The lowest number f-stop lets the most amount of light reach the image sensor. A high f-stop increases the depth of the field.witch is focal length. so I think I was wrong in the "feet" meaning f/2.8 for portrait or up close f'/16 for front and background or landscape. also set your ISO around 80 - 120 for the best exposures or pictures.

    but think of the f-stop like 2.8 in feet yes ... had to realign my brain again.

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

Can't find a way to get the date to show on the pictures


Use Canon's Zoom Browser software - it comes on the CD with the camera.
1. Open the image upon which you want the date and time.
2. Left lick on File then on Print.
3. The image opens in another window with a Properties column on the left including Shhoting Time/Date.
4. Left click on the down arrow and select your desired parameter. This can be varied if you then click on the Properties window BELOW Shooting Date/Time.
5. Left click on PRINT.
Done

New batteries are not lasting longer than a day


Battery life can fluctuate greatly from day to day. It all depends on the type of photography you are doing. For example, on one day, you spent the day taking pictures outside in the sunlight, with no flash, and didn't use your camera's screen to review any of the pictures. The next day, you spent the day inside, taking lots of pictures using the flash, zooming in and out on people's faces and reviewing the pictures using the camera's screen.
Features like the flash, zoom, LCD screen and image stabilization (IS) use a great deal more battery life than if you were to not use any of those features. This could explain why it suddenly seems like the batteries aren't lasting more than a day.
However, if your photography habits have not changed enough to potentially affect battery life, there could be an issue with either the image stabilization hardware or the standby mode of the camera. If the image stabilization (a fully mechanical feature) is malfunctioning, it could be activating when it shouldn't be, such as when the camera is on but you aren't about to take a picture.
I would try testing the camera by taking pictures using different camera settings.
  1. Turn off the flash and image stabilization, use the viewfinder instead of the LCD live view mode, do not zoom in or out. Take as many pictures as you can before the batteries die.
  2. Keep the flash and image stabilization on, use the LCD live view mode, use the zoom frequently. Take as many pictures as possible before the batteries die.
With test #1, you should see much better battery life than with test #2. If you still experience decreased battery life either way, there may be a hardware issue with the camera. Should this be the case, contact Canon Support to find out whether or not your manufacturer's warranty covers this problem.

Nikon Coolpix 5700 Over-exposure of image whilst zooming in brigh


I now have the exact same issue. When not zoomed or fully zoomed the exposure is correct, however when partially zoomed the aperture does not engage and stays fully open. So basically I cannot really use the zoom or the picture is over exposed. Note - actually about 2/3 mechanical zoom and on works, so I can use a bit of the zoom.

Suggestions?

i had that same problem. check your image size, the camera cant zoom if the image size is set to 3.1M or 2.8M(3:2)

how to change image size:
turn on camera and leave it in camera mode (picture taking mode)
press the delete/image button
change image size until camera zooms again
VGA gives the biggest zoom range

i hope this helps

Zooming with Olympus Stylus 820


Hey missy0528,
There are a few reasons your images might be grainy, one of which is your image quality is set to low. I would always have the camera set to the highest resolution possible, because you can always reduce the size of an image but you can never make it bigger. Another cause of grainy images in digital cameras is the sensitivity of the camera (ISO) is set to high. Since you are only seeing grainy images when you use the zoom the reason for the grainy images is most likely do to using the digital zoom. All a digital zoom does is crop the image much as you can do in some computer applications, and by doing this you greatly reduce your image quality. I would never use a digital zoom. Your camera has a 5x optical zoom and a 5.6x digital zoom. I would only use the optical zoom. I hope this helps!

Sincerely,
Allan
Go Ahead. Use Us.

Image Properties shown....


1: bias means voltage a neg or plus I assume the plus means more exposure.
2: focal length in feet ..if not using auto-focus
3: 4.6 feet
4: digital zoom is something I would never mess with but 3072/3072 sounds like a 3 megapixal square.
5: yes set the exposure to a fast shutter or bias in your case like - 3
6: why sure and quite a few pics in 1 minute with the right camera.
