X3F2TIFF

X3F2TIFF allows you to convert X3F files from SIGMA DP1 / DP1s / DP1x / DP2 / DP2s / DP2x cameras into TIFF. You need FlashAir or similar devices to download X3F files in Safari. If the TIFF data after conversion is too dark, try changing the max value in the settings to 500 or 300. Please use iPhoto, Snapseed, or similar apps to edit the converted photo. Only iPhone 4S is tested. It may / may not work on older devices with less memory. The support is provided via Website or twitter(@unitkay).
