TrueHDR for iPhone updated for Retina Display and iPhone 4 camera

Mel Martin

HDR (High Dynamic Range) photography isn't for everyone, but it can really help when taking pictures with extreme shadow or light. HDR images basically combine two or more pictures taken at different exposures. Using a process called tone mapping, you get a new image that displays more detail in the darker areas and restrains the areas that are too bright.

TrueHDR for the iPhone has been updated to support the full resolution of the iPhone cameras, both front and back. It now supports the Retina Display, and claims better image alignment and more natural looking results.

I've reviewed the original version and today I gave the new version a try. The updated app works as advertised, although I was a little short of dramatic scenery for my tests. The added resolution and quality of the iPhone 4 camera makes a welcome difference.

I used Pro HDR, a similar app, on a recent trip to Northern Arizona. I was very happy with the images it produced. I have now tested TrueHDR alongside Pro HDR. They are very similar. I feel that the color balance of images is slightly better with Pro HDR, but the TrueHDR images seemed just a bit sharper. Pro HDR allows adjustments after the images are merged, which is a plus. Both apps have an email feature so you can send your pictures to others. TrueHDR supports sending pictures to Facebook and Twitter as well.

Both apps are US $1.99 at the app store and worth a look if you're into HDR imaging. Unfortunately, the iPhone is not a perfect instrument for HDR photography. I'd like to see these apps offer more exposures than just two. On the other hand, they can get you a decent image in difficult lighting conditions where the iPhone camera alone can't do the job. Check the gallery for an example of how TrueHDR works.
