Doing HDRs with the 645pro (beta)

Camera App: 645pro beta

Other Apps used for post processing:

Mobile HDR - to create a HDR picture from 3 files. Most iOS HDR apps use only 2 files, one overexposed and one underexposed. Mobile HDR aims at creating HDR pictures from your bracket shots made with a DSLR. Because the 645pro currently offers the best picture quality available on the iPhone I wanted to see if Mobile HDR can be useful for photos made with the iPhone too. The answer is YES it can! But to create the files necessary for the HDR picture one must use some tricks because the 645pro offers no bracket mode shooting. So I did the following:

1) I used the 645pro film with the richest colors, which is the FC5 film.

2) I used the Neutral Density #1 filter with 100% efficiency. Currently that filter is only available in the actual beta version of the 645pro but that version is to be released soon. It runs rock stable and comes with a lot of improvements. So if you don't already have the 645pro on your iPhone I recommend you buying it. It's definitely the best camera app available, and it's a pleasure to work with it. 

The 645pro saves your photos in TIFF format as well as in JPG formt. The TIFFs are the RAW files, unprocessed, no film effects, no filters. Development of RAW photos shot with a DSLR is usually done in a so called "RAW converter" but no such app exists for the iOS devices so development is done in the 645pro itself, that's why it's called a dRAW file - a developed RAW file. The JPG file (of the same photo) is the photo with the configured effects applied, such as films and filters used.

3) In case of the old Diesel engine (above) I also created a black and white version in MonoPhix HD as well as an overexposed version in Laminar.

4) To create the HDR picture in Mobile HDR I used the black and white version created in MonoPhix HD, the JPG version from 645pro and the overexposed version made in Laminar. To create the overexposed picture I simply adjusted its curve by pulling it a bit outwards on a spot set in the middle of the line.

Here you see the original photos and the finished HDR picture

After importing the files into Mobile HDR the processing

 screen looked like this.

Here's yet another HDR picture created in a similar way than the picture on top of the page. In this case I created an underexposed version of the TIFF file to use with the set of 3 photos in Mobile HDR. Then I created a black and white version from the HDR picture in MonoPhix HD. I also tried Snapseed but I liked the result from MonoPhix HD more. Then I was opening the color HDR and the b/w HDR in Blender. The color version on the left side - the b/w version on the right side. Blending mode was "normal", with the slider set 25% to the left. This enhanced the colors and de-saturated the picture a bit at the same time.
