I recently googled depth of field adjustment for iPhone. Found this app among others. Read all the reviews. Paid the 3.99 for the full version. Have been shooting with SLR & DSLR cameras since 1969. Always enjoyed being able to adjust the amount of focus in the background. Saw the lack of being able to do so as the main failing of most phone cameras. This app is a dream come true for me! Posted photos and information about it immediately upon using it the first time. Thank you thank you thank you!
