I have used last 4 year canon 2900B printer. How to set 300 dpi printing resoluation


Canon PIXMA Manuals MG2900 series Resolution
Resolution The data in the image you have scanned is a collection of dots carrying information about brightness and color. The density of these dots is called "resolution", and resolution will determine the amount of detail your image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.5 cm). The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less detail.

How to Set the Resolution You can set the resolution in Resolution on the (Scanning from a Computer) tab of the Settings dialog.
Appropriate Resolution Settings Set the resolution according to the use of the scanned image.
Item Type Use Color Mode Appropriate Resolution Color photo Copying
(Printing) Color 300 dpi Creating a postcard Color 300 dpi Saving to a computer Color 300 dpi Using on a website or attaching to e-mail Color 150 dpi Black and white photo Saving to a computer Grayscale 300 dpi Using on a website or attaching to e-mail Grayscale 150 dpi Text document (document or magazine) Copying Color, Grayscale, or Black and White 300 dpi Attaching to e-mail Color, Grayscale, or Black and White 150 dpi Scanning text using OCR Color or Grayscale 300 dpi Important
  • If you double the resolution, the data size of the scanned image quadruples. If the file is too large, the processing speed will slow down significantly, and you will experience inconvenience such as lack of memory. Set the minimum required resolution according to the use of the image.
Note
  • When you will be printing the scanned image by enlarging it, scan by setting a higher resolution than the recommended one above.

Setting lower resolution 640 x 480 on


The S2980HD won't let you set the resolution that low. You can use any photo editing program on a computer to down-rez your photos.

Canon SD1300 setting for 300dpi size 2.75 x 2.975 how to set camera


It's not a camera setting.
DPI is "dots per inch". This only has meaning when the picture is output (usually printed, but also displayed on a screen). You can make two different-sized prints from the same photo file, and they will have different DPI settings even though they come from the same file.
A photo editing/printing program will let you control the DPI when you print a photo (and some will let you change the value when you save the file).

How can I scan a photograph, save it and then send a copy by e-mail


First do you have a scanner? if not take a digital photo with Macro settings and flash off.
If you do have scanner and figure out how to scan, scan it as a JPG or if for archival TFF. A Jpg will show and transfer better by email for the masses. after you scan it in say windows, you can save it on say your desktop and then right click it and say send to Mail recipient. If it is a big photo and you want to reprint it make sure the scan is at least 300 DPI if your scanner will go high enough scan it at the highest optical resolution that your printer has, again this is if you are planning on printing it on the other side. If you are not printing it scan anything above say 72 DPI.

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.

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?

Need to get scanned photos to between 300 and 600 dpi


What I saw first off is that although the resolution indicates 96 DPI, the file size itself between the 2 examples are drastically different. You are putting raster images into MS Word for publication work, and that is a NO NO. Word was not created for any kind of high resolution printing. It's a glorified text editor that people seem to think is an option for printing. YOU WILL NEVER GET 300 or 600 DPI images out of Word. Ever.
To create your project for printing, you need to use software more suited for the task. InDesign and Quark are examples, but they are very expensive. In my opinion, Publisher would be better for this kind of project and I hate myself for saying that.
Talk to your Printer, find out his specifications for Applications and Linescreen for Printing. The minimum requirement is 280 DPI, but if the image is placed at 100%, 600 DPI is overkill.
Oh, and try to never scan a scan... you are looking for trouble... a little thing called a Moiré pattern comes into play, and it will make you images print NASTY!
I could go on about your post all day long, but if there is anything else I didn't explain, please post again.

Creating a 300 dpi x 300 dpi file


You need to be able to change the DPI setting in the image file. This can be done in most complete photo editors, though they tend to name the procedure in different ways. In Corel Photo-Paint, you would look for "Resample Image". In the open source photo editor Gimp, look for "Scale" under "Image".

In all such procedures, what you want is to set both the vertical and horizontal DPI values to 300, apply them, then save the image. Please do save it to a different filename, since you lose some quality of JPEG images every time they are saved.
