How can one be assured that a photo you like at 8x10 format will turn out as clear/sharp when enlarged to say, 16x20 or larger??

The simple answer is use a high resolution camera--like 36 megapixcels.

But it's not that simple. Image still needs to be in focus and well exposed.

Not to be offensive, in my simplistic response, I assumed those variables to be givens. Clearly, there is more to it.

There is a plug in from onOne that was called Genuine Fractals and apparently is called now Perfect Resize... Here is the link...

Photoshop has an enlargement tool that effectively makes the image physically bigger without perceptible loss of sharpness.

Find it thus via the Menu Bar: Image > Image Size. There, use the Document Size settings to change the size of your image.

Take the image file and enlarge it to the size you are considering, crop out an important section to 4x6 or so, and print that. You can see how the quality will be.

Definitely consider Genuine Fractals (considered standard for resizing), now known as Perfect Resize from OnOne. Much better than Photoshop !

The only way you can be "assured" is to print it a see how it looks. Examining any photo close-up will reveal its shortcomings, but that's not how people usually view images. If it looks good at 8 x 10, it should look good at the next size up. A lot depends on how you're going to use it when it's printed.

There was also a program called "actual fractals" that did the same thing.

I have Onone's Perfect Resizer and I have Kneson Imagener and the Kneson Imagener does a far better job.

But there is another way to do this. I have been experimenting with PhotoAcute3 and if you have a stationary subject and can take multiple shots that can be combined, it will also increase the pixel count of the image. It needs each shot to be slightly offset from the previous shot. I just thump the camera a bit with my finger and know that pixels will then not line up exactly the same.

So what it does is to use the extra images to build a better picture with finer detail, and the results are incredible.

I currently only have the trial version which prints watermarks on the result, but what I see is very convincing. They have an offer that If you have a camera/lens combo that they don't have, that you can provide about 100 test shots of a calibration chart under a set of predefined conditions, they will reward you with a license for the product. I got accepted and have shot to upload. Waiting now for them to send me the instructions on where to upload the RAW files.

Have also used Piccure+ to increase the sharpness of the picture, and it does quite a job too.

PP tool aside, shoot in the highest resolution possible. If possible do a practice print but that could be costly.

BTW, at the size mentioned focus is critical.

Larger photos, and most art, are usually viewed from a greater distance, so appearance should be about the same.

A lot of good advice here. Mine is, use a sturdy tripod when possible. Makes a lot of difference.
