Image Quality
In Blow Up 3 we found ways to make edges even sharper without introducing computery artifacts. The images below show the difference between Blow Up 3 and traditional bicubic enlargement used by Photoshop and other image editors.

Lightroom Support
Blow Up 3 has tight Lightroom integration that supports batch processing and does not require Photoshop.

Simplicity
Blow Up-s interface is deceptively simple. Just set your paper size as you would in Photoshop and optionally set a crop region. In version 3 we kept all the rocket science under the hood.

Speed
Blow Up 3 runs faster on both Macintosh and Windows computers.

Huge Images
You can resize up to 300,000 pixels per side, the maximum Photoshop can handle. Of course, Photoshop would choke on a square image that big, but if you are making a billboard that Photoshop can handle, so can Blow Up!

CMYK
Blow Up can handle CMYK images used in offset printing and 16-bit/channel images used by professional photographers.

Presets
Blow Up has presets for common paper sizes, including photo papers and standard US, European, and Japanese sizes.

Output Sharpening
Just choose your paper type and Blow Up sharpens the right amount to compensate for ink diffusion.
