How do you take a digital photo with a specific size and resolution?

Answer 1

A:Normally a camera will have options of selecting image size in MPs (10MP, 5MP etc.). That is the count of total pixels in the resulting image and is normally termed as resolution. Actual image size in inches (for lab quality print at 300DPI) is approx. 8"x10" for 7MP resolution. One should take photos at highest resolution possible. These can always be downsized if required, but upsizing of smaller resolution image) won't be that effective. A:Depends on your camera, but using the different features like fine, auto, compact, will all change the size. You can also just simply open a digital photo in Adobe Photoshop and resize to any size. One more option is to open it on your computer (if you use WindowsXP) and go to print and it will resize it for you.

That is best done is photo software, such as Photoshop or GIMP. You can set your particular image size. In your camera, you should use the max settings, since that image is basically your "negative."

A:

You can do many tricks with digital images but the one thing you can't do is add resolution to a photograph after it has been taken. This is the main thing you have to make sure is right beforeyou take the next photograph with your digital camera.

example:

Print size: 6" x 4" or 7" x 5"

Digital image: 1800 x 1200 to 2100 x 1500 (2.2 mega-pixels to 3.2 mega-pixels)

Answer 2

You can use a variety of tools, from simple image editors (like the classy MS Paint) to dedicated image converters. Free or commercial tools.

I suggest giving AZImage a look (see reference) - it is a simple image converter supporting also advanced options if you decide to fine tune the results.
