If I take hi-res pictures with the 3040 how much can I manipulate the image on my PC to zoom in while still maintaining quality?

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.

Hi!

You need to change the PRINT SIZE and image QUALITY to have have a better picture. Try these:

Press then select (Picture Size) . You will be given an option for the number of

pixels - ranges from 0.3 to 7 Megapixel. For better print quality, select 7M.

Next thing that you need to change is the Quality. You need to go back to Menu then . These are your options for quality:



I hope that helps.

Good luck and have a nice day!

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

If you took the images at 8MP or 5MP settings, then normally you have a high resolution picture, was the picture clear at the cameras LCD monitor? As you said its like low res in your PC, please check the image file size 8MP resolution will be approx. 3Mb size, if its about that figure, then the problem is in the camera, if the file size is about 500K maybe its in the camera settings, PC cant affect resolution, unless you only have VGA card and monitor, hope this will help, thanks

Um ok. first off, chill with the images being described in inches. The DSC-S40 is way too simple to get lost with. You only have 2 options to play with. One is the resolution which you want to be as high as possible unless you have some special reason for it not to be. Two is you have 2 image quality settings to choose from(Fine and Standard). choose "fine" of course for best results. yes the files size will be a bit larger, but you get the best possible image. Remeber, this is considered a cheap camera, so you want the most it can offer.

Now about the file size anomalies. Dont worry about it. Here is the only conclusion I can come up with that sounds logical. .JPG and most "compressed" image types will never be the same size if taken from a camera unless the same exact picture is shot 2 times in a row very fast witout the camera moving. files size on a compressed image depends on the amount of color variations the camera has to render into a file. The more color variations, the more data the .JPG file contains. It is natural for file sizes from a camera to differ. If you set your camera at 4M and take a picture, and then you set it to 3M and try to take the same picture again thinking it will save space, in theory this is true, but remeber how "compressed" images are rendered. You may have had only the slightest difference of light change on the next pitcture you took . This can have a significant impact on the file size, and can result in a lower res image being bigger in file size than the higher res image. Now, if you are talking a huge difference like 3M@1500kb yet 4M gives you 500kb, then you either have it set to "standard" quality, or you are really lost in this stuff.

But anyway, I hope this is plenty of info. And makes plenty of sense to anyone who understands compressed images.

Press the "T" for telephoto and get closer to the subject. Optical telephoto zoom is like using a telescope to get closer to the subject before taking the picture. With optical Telephoto zoom you can maintain the full resolution and quality. After you have used all of the optical Telephoto range, the camera will continue to enhance the image with Digital Zoom. This enhances the image inside the camera by reducing the resolution and expanding fewer pixels to fill the same image space. Use the "W" Wide-angle button to back-up away from the subject or get a bigger area into your picture. You can even ZOOM IN on a picture in the playback mode for a better look at the details. Touch the Magnifying Glass Icon. Use the Arrow Keys to move around the display area.

SHQ1 and HQ are two different levels of compression to make the file smaller. This will have a great impact on the image quality. Generally on Olympus cameras, this is what those letters mean: TIFF (highest (best) quality) generally not used. Files are HUGE and takes a long time for the camera to save the image to the card. SHQ (super high quality) you probably wouldn't be able to tell the difference between this and the TIFF HQ (high quality) which is lower quality than SHQ SQ (standard quality) which is lower quality than HQ SQ1 (standard quality 1) which is lower quality that SQ SQ2 (standard quality 2) which is lower quality that SQ1 A 2048x1536 only seems large because most people have their monitors set to 800x600 or maybe 1024x768 (that's what I have mine set at). This will seem to make the image REALLY LARGE! It only seems that way because you have to scroll around to see the image. If you want to print images, you'll want all the resolution you can get. If you want to display them on your screen (slide show,WEB page) then you don't need large images. You would just need to resize them down. However, since you may want to both, getting a camera with a higher resolution gives you the choice to do either. Usually, the higher resolution cameras have better lenses and generally take better pictures. On my camera (the Oly 2100), I always shoot at the highest resolution and the least amount of compression (SHQ on my camera). This allows me to do almost anything with the image. Nowadays, camera media (smart cards) are fairly cheap, HD's are DIRT cheap and CD-Rs are very cheap. If the images are "keepers", then I personally would want to start with the best image possible and store the images on CD.
