PixelCalc is a very convenient tool for anyone working with digital images, whether from a Camera, scanner or other input device. It is especially useful for graphic designers who work with both Web and Print media. Either of these two areas of media frequently require conversions from Pixels to Inches and Inches to Pixels along with a desired Resolution (i.e. hi-res, medium-res or low-res).

Now includes a Proportional Calculator and three useful Reference Charts.

Proportional Calculator
The Proportional Calculator will instantly calculate enlargements or reductions of images, photos, artwork, layouts, or any kind of design. Basically, anything that needs to be resized accurately while maintaining perfect proportions, the Proportional Calculator will do it.

Contains the following handy reference charts:
-Maximum Print Size per Megapixels (different resolutions)
-Maximum Print Sizes (in inches) by Megapixels @ 300ppi
-Shutter Speed Chart (Useful camera tool for perfect shots!)
-See the charts in the app for detailed reference information

App works but needs some updates

What it does have seems to work. It would be better if the user would be able to enter the megapixel and dpi as an input and not a slider. Many cameras have larger megapixels then this app allows. It would be better to enter a dpi as the slider does not allow enough choices. The proportional calculator should auto calculate x and not need to press resize. It would also be helpful to have a choice to get a list of different size.

Pixel Calc icon not showing. Shows up as a generic icon-iOS 10.

Great little app

Perfect for when away from Photoshop or stuck at a party and asked questions about megapixels, etc. Love the new proportions calculator, wish all my fellow artists would use this app, save me the explaining.
