I have a photo on my iPhone that I’d like to print, but it doesn’t look very good. I have Photoshop CS5. What can I do to get the best possible print from an iPhone image, and are there limits on print size or resolution that I should expect?

There are a few things to look out for when making sure your iPhone photos are the best they can be for print, but don't expect to be able to get very large prints (at least high quality ones) made from an iPhone photo. Make sure that if you are using a photo app that it also saves a high res version so you're not stuck with their poor output (many apps really degrade resolution). Other apps have a setting where you can set what kind of resolution you want. Make sure it's at the highest setting.

Oh and you don't need to print at 300DPI or even 200DPI. In many cases 100DPI will be just fine. If you're doing a canvas print resolution isn't as critical since you'll have graininess anyway.

You can often improve an iPhone photo for print, but there are limits. The biggest issue usually isn’t pixel count alone—it’s the phone’s small sensor, which can reduce clarity and add noise, especially in underexposed shots.
To get the best result:
- Start from the highest-resolution original you have. If you used an app, make sure it saved a full-res file, since some apps reduce resolution heavily.
- In Photoshop, adjust exposure, contrast, saturation, sharpening, and noise reduction carefully.
- Don’t overdo sharpening or noise reduction, since your printer or print lab may add some of its own.
For printing, very large high-quality prints may not look great from an iPhone file, but smaller prints can still be fine. You also don’t necessarily need 300 dpi; depending on viewing distance and print type, 200 dpi or even 100 dpi can work. Canvas prints are especially forgiving because fine detail matters less there.
So: use the original full-resolution image, make basic tonal and noise/sharpness corrections, and keep print size expectations realistic.
