When I transfer my photos from my camera to photshop elements, are this tthe sizes: 34 x 23 inches and 72 dpi.
I want much more dpi. How can I get that? Now I change every singel photo in photoshop. Is there an easier way?
when I transfer pictures from an other camera (kodak) I get 230 dpi. How is this possible???

DPI (dots per inch) is an output parameter and has absolutely no meaning to the camera. It has meaning only when you output the photo to a printer or screen.
Let's say you took a photo that's 3000 pixels on the long side. If you then make a 4x6 print, you're putting 3000 pixels into six inches so you're printing at 500 dpi. If you make an 8x10 print, you're putting 3000 pixels into ten inches so you're printing at 300 dpi. Either way, you're printing the exact same picture, only at different dpi settings.
The camera has to put something into the dpi field, so it defaults to 72 which is often used for computer screens. Just about any program you use to print your photos can change this number without affecting anything else.
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.
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.
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.
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.
Sounds like Photoshop's setting, or default setting, is to import picture at its maximum size. If you RESIZE pic on Photoshop, it shoud automatically increase DPI while reducing physical size.
The other thing to be aware, TZ3 defaults to a certain jpg compression. You can minimize compression of data with settings options on TZ3, but I doubt this has anything to do with your PhotoShop issue.
Also, in SIMPLE mode you can select a physical size for photo, even after pic is taken(resize), on camera.
Many cameras will take pictures at only 72 dpi. Changing the resolution causes the camera to change the size of the picture in terms of pixel dimension (ie 800x600 vs 640x480) but always at 72 dots per inch. A photo editing program like Photoshop can change the resolution to whatever you need.
Do not be too bummed out. The DPI reported in the EXIF data does not mean all that much. What does matter is the total number of horizontal and vertical pixels in an image and how this relates to the output size. For instance, your camera is capable of producing a 2304 by 1728 pixel image. This works out to about 220 DPI when printing an 8 by 10 inch picture. If you look at this the other way around, image editors will indicate an image size of 32 by 24 inches for an image taken by your camera (2304/72 and 1728/72). It is doubtful you will print at this size. Image software will take advantage of the full resolution when printing an 8 by 10, or 11 by 14.
