Re: Image Quality decrease

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.

Hi i have an Olypmus UZ800 and it takes only 72 dpi photos, how can i change to 300 dpi, i must insist that i use FINE picture quality

Please don't confuse the input resolution with the print resolution. DPI controls how many dots per inch are printed. It has nothing to do with how the picture is taken, that's controlled by the input resolution (also called image size). The image quality has nothing to do with either, it controls how much the image is compressed before being stored.

Input resolution (image size) is controlled by the "IMAGE SIZE" entry in the Shooting menu. 14 megapixels is the best this camera can do.

Image quality is controlled by the "COMPRESSION" entry in the Shooting menu. FINE is the best quality, least compression.

The DPI is controlled by whatever program you're using to print your picture. Were you to print a 14-megapixel picture at 72 DPI, you would get a picture that's almost 5 feet by 4 feet. Were you to print the same picture at 300 DPI, you would get a picture that's about 14 inches by 11 inches. If you wanted to print a 6 inch by 4 inch picture, you would have to print at about 700 DPI.

I have taken only 8 snaps in my samsung L313 camera and for the next snap thr is a message as memory full... pls help me to come out of the problem

Hi, If you just bought the camera I'm betting you maybe didn't get a memory card yet, if this is so you will need to adjust the picture quality-the higher the mega pixels the more memory each shot takes-and working with just the internal memory alone that sounds like what is happening there. Just go into menu and select an" image size " that takes less space example: in menu one of the first things you may see are 12M,8M,6M,6M,etc.. ( when you successfully do this you should see an icon indicating how many pics you have left to shoot-this will increase and decrease according to image Size. I hope this helps, please comment back and thanks for asking FixYa, good luck prodzilla

Without a memory card, does the camera really only take 13 pictures and if so, how do you change it to take more pictures?

The Nikon Coolpix S230 has only 44mb of internal memory, there is no way to expanding it, you should use a memory card.
If you want to take more pictures without using a memory card, you should decrease the quality of the pictures pressing the menu button then selecting 'image mode'. If you go from 'High' or 'Normal' to 'pc screen' or 'tv screen' setting you can take more pictures because the files will be smaller, but also the resolution will be lower so if you print the photos the quality will be not so good. Just try and see if that helps, bye

We have a Technika SH-8360, and it appears that the image quality has decreased dramatically, and now the pictures are of a lot lower quality and much grainier than before. What would cause this? Would...

Cameras don't lose megapixels but users can change the settings for them. Go into the menu and see if your camera is set for the maximum number of megapixels and the highest picture quality.

It depends on the quality of the image and the number of mega pixels at which you shoot photos. HP Photosmart M517 shoots at up to 5 mega pixels + there is an additional setting called "5MP Best". 5MP setting creates images that are around 1.5MB - 3.5 MB in size. So, assuming 2.5 MB as an average, you'll get around 52 images per 128 MB at the best possible quality. You can do the other math. However, the camera always displays an "estimate" of how many more pictures you can take.

Now if you want to increase the number of pictures you can take you should decrease the image quality. 5 MP regular might give you upto 64 images per 128 MB, 3 MP may give you uptp 128 images per 128 MB (these are all approximations that evaluated based on my experience with this camera). I suggest that you don't go below 3 MPotherwise you'll get images that look OK on screen but not good for printing.

The "picture remaining" number on the display panel does not decrease after you take a picture or record a message. Why?

The camera is operating correctly. The total number of pictures you can store depends on your pictures' content and messages' length. So the number doesn't always change, especially when you're using standard image quality.

E-mailing photos

JPEG format storage is ideal for posting your photos to the Internet and for e-mailing them to friends. (It’s also useful for archiving when you've finished editing them and need to save storage space.) The compressed images still look good on-screen and contain a relatively large amount of information in the shrunken file. JPEG storage is great for maximizing space but not for maintaining image quality. If you want to get smaller files for archiving, use minimal JPEG compression (high quality/low compression). The ideal compression is lossless, which means there's no discernible drop in image quality even though the file size has decreased.

Pictures are underexposed

When you are photographing scenes with mostly light objects (for example, snow, water, and sand), the picture is usually underexposed (darker than it really is). The camera meter registers the brightness of the scene and tries to set the camera lens and aperture for an exposure based on average brightness levels (18% reflectance) causing it to underexpose, as in the following picture. When you are photographing scenes with mostly dark objects (for example, shade, shadow, and overcast skies), and very few light objects, the camera may overexpose the image, causing it to be too light. If you have a flash on your camera, you can compensate by adding "fill flash" for some extra light. If your camera has an exposure compensation adjustment, you can increase or decrease the exposure to correct for these exposure problems. Increase the number to make the image lighter, and decrease the number to make the image darker. You may want to try a series of shots with different exposure compensation adjustments to get a feel for how much difference these adjustments make.
