This week I’ve decided to add Big Photo to my toolbox. It’s a superb Universal app that lets you upsize or downsize an image. The full feature set is giving in the description.
1. Big Photo provides capability to view large images or photos over 20MPs (like panoramas) up to 110MP for latest iPhone/iPad, as well as small icons, all in full resolution, and zoom to pixel level.
2. Big Photo provides multiple options to enlarge or down size your photos or images to any custom sizes.
3. Big Photo provides crop tool to crop a “small” portion out of your full resolution photos/images, and produce high quality “blow up” results.
4. Big Photo provides Rotate/Flip (iOS 6.0+) at any angle, support alpha channel (transparent region).
5. Big Photo provides Batch Resizer (iOS 6.0+) – resize tens or hundreds of photos in batch mode. (Optional)
6. Work as your device’s universal image tool: for images in your emails or other apps, “Open in…” can launch Big Photo to view or edit.
7. Special algorithms to handle big pictures and large images: iPhone 4S/iPad 2 mini – 90MP+, iPhone 5/iPad retina 110MP for unlimited fine detail zooming. Similar sizes for crop – sum up the sizes of source and result images. 600% upscale: 8MP=>48MP+ on iPhone 4s/5/5s, iPad 2 or later. For other devices, adjust the sizes accordingly.
There are two reasons I end up using this app, one for downsizing, and one for upsizing. I have a rather limited data plan (a mere 200 meg) since I’m usually near a wifi connection, but every now and then I have to use the cellar data. When choosing to post a photo to Twitter or Facebook I’ll always do a drastic downsize of the image to avoid excess data. My friends won’t see the highest quality image, but I won’t end up paying more for uploading too many big photos.
On the other side of things, I use the upsizing to deal with output from many other apps I use that produce low resolution images. These are often apps that produce some odd effects and the authors didn’t take the time to have them produce full resolution output. [I’m not blaming software authors – I know how things are as I sit around programming all day. There are always decisions to be made, skills to learn, etc.]
One example of this is a recently released app call Trimaginator which creates interesting images that are typically around 640×853 pixels when exported. I will upscale those images so that when I use it in other apps I’ll end up with high resolution photos (useful if you plan to print them or want bigger images on the web).
The interface is so simple that you don’t really have to think. You just choose your output size and press resize. The app then automatically saves the new image to your camera roll. Doesn’t get much easier than that!
This app is currently on sale for just $1 (usually $2). It has a few in-app purchases that allow you to do bulk resizing on multiple photos. This could be very useful for professional, but the vast majority of people probably don’t need that feature.
