DPI resolution My pictures are always set at 72 dpi no matter what image setting I use. I have friends with much lesser cameras that take better pictures and their dpi settings range from 230 to 300. HOw can I change this setting?

The dots per inch setting (DPI) is meaningful only when printing the picture. As such, the camera simply fills in a default value of 72. You can change it in Photoshop or any other photo editing program. The resolution setting on the camera only changes the number of pixels in the picture, not how you print it.

As this handset is an old model you need to check the manual for the supported file format, and resolution support. You can check the DNS settings from your service provider.

Set the camera for the highest megapixels and picture quality to the highest level.

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.

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.

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?

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. Regards.

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.

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.
