Resolution I want to know how to change the resolution, after I have already taken the picture, and want to print it out, but need a higher resolution so it will be clearer?

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

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.

I dont know what resolution your camera is, but make sure you have it set at the highest it can go. The higher the resolution the better quality the picture. I had a 12mp camera but you could set it as low as 4mp which is ok for snaps but if you are uploading or printing then you need to set your camera to a higher resolution if you can. Read your instruction book it should tell you how to configure your settings there. If it is an old camera that cant be changed then maybe its time to invest in a higher mp camera perhaps 8mp 10mp or even 12mp

You can choose higher resolutions under picture quality in the camera menu.

All cameras have multiple settings for picture quality. For example if you email a lot of pictures select a lower resolution. If you have "poster" size prints made select the highest resolution you camera will do.
Go into your cameras set up and select the highest resolution you have. should be about 12MP.
You have a high quality print with that.

You have to scan the pictures with a higher resolution to be able to print them in a larger format with acceptable quality.

If your default scanning setting is, say, 150dpi resolution, and you want the picture to be enlarged twofold, then you have to increase the resolution to 300dpi. If you have 300dpi now, increase it to 600dpi.
Some scanner utilities do a fully automatic scan - then you have to find the automatic scan settings and change the default resolution. Or better yet, find an option for a non-automatic scan, where you are presented with various options after the preview scan has been done. There you can usually set the desired size, resolution, improve contrast, sharpness etc.

Generally, the higher the scanning resolution, the more detail you have on the picture, and the higher magnification you can obtain when printing without quality loss.

But there's a catch - a picture in higher resolution produces a bigger file on disk - the file size grows faster then the resolution - a two times bigger picture will be four times bigger on disk. So you have to make sensible choice.

Ok, this is a very easy procedure..
While in picture taking mode, press the set button and it will activate the controls to choose the image resolution. If you select a higher image size or number, it will improve your quality of picture as the number of the resolution you choose gets higher. Simply use the side scroll and the up/down scroll on the back... that will do it for you!

using the RAW setting will give a higher quality photo, the other formats compress to jpeg causing you to loose some of the original photo information. the ZoomBrowser EX program allows you to edit the RAW image, I recommend getting the large prints done at Kinkos or some place like that. I've gotten poster size prints done that look very clear. Use a tripod to combat camera shake, it is very apperent at that size of print. Also a low ISO to help reduce noise.

I take it that 'Shutter Fly' is an online print service that right?
Check out thier help file with regard image specifications requirements
Then consult camera manual with regard setting the correct rez

ive asked the same thing.. if you find out how.. let me know! I would like to know that I can print out as wall art! :(
