Do you need camera resolution?

When shooting photos with your digital camera , your camera resolution can be designed to meet your needs. With so many options, it can be a little difficult to answer the question: Which camera resolution is needed?

For photos you only plan to use on the internet or send e-mails, you can shoot at low resolution. If you want to print the photo, you need to shoot at a higher resolution .

However, if you are not sure if you are planning to use the photo, the best advice to follow is to draw only the highest resolution picture available on your camera. Even if you don’t want to print the picture first, you can decide to print it on the street for six months or a year, so shooting at the highest resolution with the shortest of your photos is almost always the best choice.

Another advantage of shooting at the highest possible resolution is that you can later cut the image into smaller sizes and without details and image quality.

Select the right camera resolution

How you determine the camera resolution you need for at least one print to print depends on the print size you want to do. The table listed below will help you decide on the right resolution.

Before looking at the combination of image print sizes, however, keep in mind that resolution is not the only factor between image quality and print quality.

These factors also play an important role in determining how your digital photos will look on a computer screen and on paper.

  • The right light
  • Lens quality
  • Camera stability
  • Auto focus on the right subject
  • Proper shutter speed for moving or stationary subjects
  • Clean equipment

Another factor that plays an important role in image quality – which you can determine is how to create a print – is the camera’s image sensor .

As a general rule, a camera with a large size image sensor can produce high quality photos versus a camera with a small image sensor, no matter how many megapixels the resolution of each camera offer .

When buying a digital camera you can help determine the size of the print. If you know that you want to print big all the time, then you need to buy a model that gives a large maximum resolution. On the other hand, if you know that you only want to print occasionally, small, you can choose a digital camera that provides an average resolution, which probably saves some money.

A camera response reference chart

This table gives you an idea of ​​the amount of resolution for both average quality and top quality prints. Shooting the resolution listed here does not guarantee that you can print a top-quality print in the format listed, but the number will give you at least one starting point for determining print size.

Resolutions are required for different print sizes
The solution Average. Quality Very good
0.5 megapixels 2×3 inches N
3 megapixels 5×7 inches 4×6 inches
5 megapixels 6×8 inches 5×7 inches
8 megapixels 8×10 inches 6×8 inches
12 megapixels 9×12 inches 8×10 inches
15 megapixels 12×15 inches 10×12 inches
18 megapixels 13×18 inches 12×15 inches
20 megapixels 16×20 inches 13×18 inches
25+ megapixels 20×25 inches 16×20 inches

You can follow a simple formula to help you determine the best shoot resolution for any size print. The formula assumes that you will create a print at 300×300 discs per inch (dpi), which is a typical print resolution for high quality images. Multiply the length and height (inches) of the image you want to create by size 300. Then divide by 1 million to determine the number of megapixels to record.
