Image Junky transforms your camera-mounted iPhone into a parallax corrected viewfinder for any camera or format. Mount your iPhone on your main camera and use it as a live view finder! Enter the offset distances of the iPhone lens from your main camera lens and the app does the math, adjusting the image to keep your compositions accurate. You also get tap to measure LiDar distance information for easy focusing. There are no other apps that have these features. Check out the instruction page for more information on how to mount the iPhone and measure the offsets.

Simulate real optical filters in black & white. This app uses custom CIColorKernel shaders to modulate grayscale luminance based on color vector similarity—accurately mimicking red, yellow, green, blue, and orange filters as used in film photography. Then, if needed, save the filtered image with filter information. Then, swipe left and find an automatic shutter speed calculator for applying various ND filters And that's not all; keep on swiping and you can simulate pinhole photographs before shooting!
