Re: Resolution

Resolution refers to the number of pixels or dots per inch (dpi) in an image. Basically, the more dpi that a photo has, the sharper an image is. High resolution is important if you are going to be printing photos (look for a photo-capable printer that has a high resolution, say 4800 x 1200 dpi). If you’ll be e-mailing your images, you may want to save your photos at a lower resolution for faster file downloads. Digital camera resolution is measured in megapixels (1MP equals one million pixels), so the higher the MP capacity a camera has, the higher quality of images it will produce. Generally you can take good photographs with a 3MP camera.

300 dpi image change


Yes you can. But 300 dpi is nothing. You could compare this to a question like, fits a yard in a football field.
When talking about 300 dpi, you also must know how big a picture has to be.
According to the manual, your camera can shoot pictures with 4288 by 3216 pixels. When you want to print 300 dpi that is 14 inch by 12 inch pictures. If you want to shoot pictures for smaller results like 6 inch by 4 inch or 7 inch by 5, you can chose a smaller resolution.
Don't be confused by the technical terms of 300 dpi. This is only used in the printing industry. I already printed till 4 times the resolution that was theoretical possible, and still the pictures look very good.
If you have a great picture, shot in the highest resolution, you should be able to make a print of more that 5 or 6 feet and still have a great picture

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.

Date stamp option in menu will not highlight to change it just skips past it change daye and time


For some cameras this option only works when the camera is set to a specific resolution. Some calle this resolution "Postcard" resolution, and is usually 1200 pixels width. Try setting your camera to its other resolutions to see if this ocrrects the problem. Suggest that you start with 1200 x 900 resolution. Keep in mind that this 1200 x 900 gives only 1 megapixel resolution. Most newer cameras are capable of taking much higher resolution pictures, so this may be a trade-off if you want to use the date stamp option.

Confused about Resolution Sony DSC-T7


2.2 MB is the size of the file on your hard disk. Being a .jpg, it is a compressed file. The file size does not reflect the size of the image stored inside the .jpg. Yes, the size sounds about right. It will increase or decrease depending on how much detail there is in the picture. If, for instance, your picture is made up of nothing but uninterrupted blue sky, the disk file will be quite small - as the .jpg does not need to store much information (the more repetitive information, the smaller the file). On the other hand, if your photo consists entirely of nothing but blades of grass, the disk file will be comparatively large. When you see "DPI", that refers to print resolution. So, since you're not printing, but rather, viewing onscreen, Photoshop "assumes" a convenient "screen resolution", as though you printed on the screen (don't ask!). If you look at the other settings, you'll note that Photoshop also thinks your photo is 36" wide!!! You adjust the DPI (or photoshop will) when you print. Till then, it doesn't mean much. Let me give you an idea of your image's possible DPIs. Assume you really want to print a 36" photo: 2592/36" = 72 DPI If you make the picture 12" wide: 2592/12" = 216DPI At 10": 2592/10" = 259.2 DPI At 8" 2592/8" = 324 DPI How do you get my photos above 200 DPI? By printing the picture small enough, less than 12.96" on the wider side. See calculations above. The resolution at which you shot the image (2592X1944), will not cause blurriness. As for the cause? There could be any number. Was the subject moving? Were you? Did you shake the camera while shooting? Is your shutter speed too slow? Should you have been using flash? Is the camera autofocusing correctly? Are you waiting for the autofocus to lock before pushing the shutter the rest of the way? Etc. Hope this helps somewhat...

Memory cards


You may be able to store up to 110 images if you use the camera in its lowest resolution mode. In high resolution, you may get only 24 shots. We wish we could tell you precisely, but it depends on the exact size of the file created by a given camera, as well as the resolution that you select. Keep in mind that Secure Digital, CompactFlash, and SmartMedia memory cards are competing products and are not interchangeable. You'll find a few cameras that are compatible with more than one brand, but generally when you buy a digital camera today, you'll be making a commitment to work with one type of memory card. Use the attached chart to determine the average number of photos that Secure Digital memory cards can store (compatible with most HP digital cameras)

I'm getting really confused with the resolution stuff


The C4000 is a 4 megapixel camera and can produce photos that should produce very nice 8 x 10 photos. 11 x 14 prints may be pushing it a bit. Your cameras should be set for 2048 x 1536 and the .jpg compression should be set to "Super High". Better yet, that camera can produce TIFF format. For photos you plan to print, use the TIFF format. The other half of this process is the printer. Most inkjet printers have a number of settings. Make sure that it is set for photo paper and be sure to use glossy photo paper. If you can print a 8 x 10 print in less than a minute, your printer is not set right. If it seems like it is taking forever, it is set right. .................... Using Photoshop Elements 2: Open your photo into Elements. Click Image, Resize, Image Size Remove the checkmark from "Resample Image" Change resolution to 300. Notice that the width height is about 5 x 7 inches. So if you print that photo at 300 dpi (dots per inch), you will get an outstanding 5 x 7 print. Most inkjet printers produce their very best outputs at 300 dpi. At 200 dpi, the image is still quite good. When you get below 150, you will start to see changes in quality. Now set the Resolution to 200 dpi and notice that the output size has changed to about 8 x 10 inches. Now check to see how it will look on paper. click OK. Click File, Print Preview You can verify that the photo fits on the paper and that the paper is correct (horizontal/vertical). Now print the photo. The next window that opens should let you get to your printer properties and you can verify that you have the printer set for it best settings and that paper is set to photo paper.
