What Is Pixel Resolution? | Digital Cameras


All digital images have a certain resolution
that the camera will save the photograph at. It’s the important thing to remember if want
to make your photograph bigger, if you want to blow it up. A camera like this, a high-end DSLR, the pixel
resolution is going to be somewhere around 7,000 pixels by 5,000 pixels. Keep in mind the majority of the internet
is about between 800 and 1,000 pixels wide for most images. So, 7,000 by 5,000 is a lot of detail to work
with. But again, you have to remember that photographers
are using this for magazines, billboards, and things like that because they need that
pixel resolution. Something, for instance, like an iPhone, which
I have right here, is going to have a pixel resolution closer to 2,500 pixels by 2,000
pixels. The reason for that is the sensor in this
camera is much, much smaller and has much less resolving power than the sensor in this
camera. Resolving power just relates to the actual
resolution that you can pull out of an image. Again, if you’re only posting your photos
on the web, you’re not going to need to worry about resolution so much. If you want to get them printed large, it’s
important to remember that you need to be using a camera that is going to have enough
resolution to allow you to do that, and an iPhone might not be your best choice. That’s just some basics about pixel resolution.
