Could you specify what exactly you mean by "quality"? –  Volker Siegel Apr 4 at 19:24
    
No. No matter what you use, the software has to make up missing pixels some how. Some apps are better at it than others, but ultimately, it will not be as good of quality as it would be had you had the original image in that size to begin with. –  DA01 Apr 4 at 19:28

When you increase the size of an image (whether in Photoshop or any other program), the program has to add pixels. Since the information about what exactly what color those pixels should be doesn't exist in the original image, the program has to guess what it should add. There are different ways to make those guesses, but they are always nothing more than a guess, so the result will never have the same quality as a full-size original would have had.

It would be like taking a short story and applying a computer algorithm to expand it into a book. The computer might make some pretty good guesses, but the "book" is never going to read as well as one that was created in full by an author.

In either case, a skillful human (digital artist or author) can take the computer output and turn it in to something of good quality, but that's not something computer algorithms are currently capable of.

I assume that you tried the standard method already, with the best settings, and you are saying that result is missing "quality".

Depending on what you call quality, maybe the original image just does not have enough quality for an image in the larger size?

It could help if you add example images to explain the problem.

Unfortunately, no. thats a 500% increase in size.

if its a completely geometric image with sharp edges, under Image Size you can select "Preserve Hard Edges" under Resampling.

But any antialiasing and it will have pixel degradation.
