Re: DPI resolution

Menu- camera set up- picture quality- try to locate picture size using menu button switch. RAW file is the best but it eats too much memory.

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.

Change 72 dpi to 300 dpi

Your camera cannont shoot at either 72 dpi or 300 dpi. It shoots at whatever resolution you have it set for. Dpi (dots per inch) is a print specification, denoting how large (or small) your pictures are printed.

The DSC-W100's highest resolution is 3264x2448. Printed at 72 dpi, it can generate a print bigger than 40x30 inches, albeit a bit grainy. Printed at 300 dpi, you can generate 10x8 inch prints.

Again, dpi is a measure of how you print pictures. It has no bearing on how you capture images with your camera.

They keep telling me that my picture is too big . It is a 4X6 picture on my computer.

More information on exactly what you are trying to do would be helpful... But it sounds like it's a resolution problem. Computer monitors usually display 72 or 96 dpi (Dots Per Inch) Printers usually print out images at 300 or 600 dpi Some newspapers are printed at only 50 dpi Scanners can scan a photo in thousands of dpi...
If your photo is a 4x6 at 300dpi, then when they try to display it in 72dpi, it will display as just a bit larger than a 16x20" image
When you are scanning a photo to email, then make sure that you set your resolution to 72 dpi to display on the screen - or vice versa, if you are going to print something, make sure you scan it at 300dpi
If you have any graphic programs, (Microsoft offers "PowerToys" for Windows XP) you can open the file in that, and usually find a setting for the Image Size that will let you set a new DPI. It's usually ok to lower an image's dpi - but there is a loss of quality anytime you try to add dpi, since you are forcing the computer to "guess" what all those hundreds of dots should look like, and they aren't good at that.

How do I take a picture at 300dpi

The DPI are not a user allowed settings. Normally DPIs are factory defined.
You can change the DPI using software. Normally the image administration software and advanced softwares can allow you to change it.

Remember an important issue: DPIs are a printing matter not an image quality matter. Yo can set an image to 300 DPI and the same to 72 DPI and you will see no difference between both images.

A good camera and your skills will allow you to take high quality images.

Why does the FinePix E510 pictures download from the camera at 72 dpi when the camera was set to take 500 megapixel photos? I cannot find any way to adjust this in the finepix manual or in online help. I...

A couple of things - I don't think you mean 500 megapixels (that is a lot!) but I assume you mean you expected a high resolution image. You may have it! The dpi setting is largely irrelevant (for photographers) as it simply relates number of pixels to a (notional) print size. Thus an image that is 3000 pixels wide (say) would print out to 10 inches at 300 dpi (3000/300) or 40 inches (approx) at 72 dpi (3000/72). the image has the same information /resolution - it's just "spread" further on the larger print. You can easily change the nominal dpi in e.g. Photshop Elements but it won't affect your image quality.
If however you are getting low resolution images when setting the camera differently that's something different. I would need extra info to help there but pssibly check if the camera was set to RAW and maybe you were looking at the (small) JPEG usually saved with it?

Photo resolution

Sony H1 takes photos at 72 dpi by default. But the picture quality will be good. if you want to convert it to 300dpi open the picture in adobe Photoshop and select image size and change resolution to 300 dpi. but the file size will be very high to up load. if you want to reduce the file size select the image size in adobe photoshop and reduce it according to your requirement. if my solution proves good please rate it.

How do I increase the dpi on TZ5

Hi - When talking about resolution in digital photography there are two main meanings.
One is the "pixel count resolution" and the other "embedded resolution". So for example your camera could record 2272*1704 as the actual pixel count resolution and set 72 as the embedded resolution that tells other software (for example photoshop) what the intended use of the picture will be. 72 ppi is the default for web pictures. You can change this in photoshop by going to the "Image" tab & select image size. The window that opens will show you the pixel dimensions i.e. pixel count resolution and the document size & resolution 72. You just change it in your software to 300 for printing. In Photoshop you can change the default to 300 by going "edit", "preferences", "units & rulers" and setting the values for "new document preset resolutions".

So for your camera the embedded resolution is 180 which you can only change in your PC software.

This is a complex subject, I recommend looking at the following web page:

Have you looked at the number of inches that 72 dpi is spread out over? 72 dpi is the standard default setting for any digital camera. What matters is the size that you actually print it at.

Higher res pics on OPtio S4

This resolution doesn't matter to most software. It doesn't change the image at all, just occasionally the size it is displayed (only if the software scales the image according to the resolution, which most don't). This having been said, I doubt there is a way to change it in camera. But you could certainly change the XResolution and YResolution meta information with any good EXIF editor. Also, Photoshop can do this too, but it will mess up other things in the meta information. You should be able to script either to apply this change to a number of photos at once.
