Not long ago, there weren't many options for increasing resolution other than using your editing software's built-in resampling methods. Today, we are faced with more possibilities than ever. Of course, it's always best to capture the resolution you need right from the beginning. If you have the option to rescan an image at a higher resolution, by all means, you should do that before resorting to software solutions. And if you have the money to put into a camera capable of higher resolutions, you might find that money is better spent than if you were to put it into a software solution.
Having said that, there are often times when you may have no other choice than to resort to software. Most software only has one command for both resizing and resampling.
Resizing an image involves changing the print dimensions without changing the total pixel dimensions. As the resolution is increased, the print size becomes smaller, and vice versa. When you increase resolution without changing pixel dimensions, there is no loss in quality, but you must sacrifice print size. Resizing an image using resampling, however, involves changing the pixel dimensions and will always introduce a loss in quality. That's because resampling uses a process called interpolation for increasing the size of an image. The interpolation process estimates the values of the pixels the software needs to create based on the existing pixels in the image.
Increasing Image Resolution
Resampling via interpolation results in serious blurring of the resized image, especially in areas where there are sharp lines and distinct changes in color. Another aspect of this issue is the rise of the smartphone, the tablet, and the corresponding focus on the device pixel. These devices contain two to three pixels in the same space occupied by one pixel on your computer screen.
Moving an image from your computer to a device requires you to create multiple versions of the same image eg 1X,2X and 3X to ensure they display correctly on the device. Does one increase the size of the image or increase the number of pixels? Photo editing software generally offers a few different interpolation methods for calculating new pixels when an image us upsampled.
Here are descriptions of the three methods available in Photoshop.
If you don't use Photoshop, your software probably offers similar options although they may use slightly different terminology. Note that there are more than just these three methods of interpolation and even using the same method in different software may produce different results. Photoshop offers the best bicubic interpolation of any other software that we have compared. A few other image enhancement programs offer other resampling algorithms that claim to do a better job even than Photoshop's bicubic method.
If your software offers one of these resampling algorithms or another one not mentioned here, you should certainly experiment with them to see which one gives you the best results. You may even find that different interpolation methods produce better results depending on the image used. Some folks have discovered that you can get better results when upsampling by increasing the image size in several small increments rather than one extreme step. This technique is referred to as stair interpolation. One advantage to using stair interpolation is that it will work on bit mode images and it requires no additional software other than a standard photo editor, such as Photoshop.
The concept of stair interpolation is simple: Then you would repeat the command as many times as it takes to get to the size you need. Obviously, this can be tedious if your software does not have some automation capability. If you use Photoshop 5. Page content loaded. Sep 2, 6: Sep 4, 5: What you are looking for is called "resizing", more precisely here "upsizing" increasing the pixel dimensions of a pic and is easily done this way:.

I am very grateful to you and the others for taking the trouble to reply to my question. Sep 4, 1: In the opening dialog, add a letter for instance "A" at the end of the name since this is a new photo that we want to sit right beside the original, if you choose to reintroduce it into iPhoto, and then into the same Event , and change the destination to "Desktop" ease of access , and from where you can drag-drop the pic back into iPhoto later.

Sep 4, 3: In fact, when performing an upsizing on a lo-res image, there will be some gain in the visual quality of the photo Sep 4, 6: Sep 5, 5: This is incorrect: Here ya go: And then " evens out the appearance of the original pixels " is what i call a gain albeit small in visual quality: Sep 5, 6: Sorry, but everything above applies to all versions of iPhoto between at least 9.
