Will Lightroom 4 support all my files? Maybe.

Updated 9/22

I’ve been getting a lot of emails asking whether Adobe Lightroom 4 (and/or Adobe Camera Raw 7) will support the file format for certain new cameras.

In Lightroom 4.1 or later, you can import and work with TIFF 16-, 24-, and 32-bit floating point images – also known as HDR (high dynamic range) images. You can use the Develop module controls to edit HDR images, and then render the images for export or printing as 8-bit or 16-bit images. Lightroom can now import DNG format HDR images, but you need to make sure the images are processed version 2012.

To keep things simple, here’s the complete list of currently supported file formats:

• TIFF (8 bit, 16 bit, 32 bit)
• PSD (8 bit, 16 bit)
• RAW – Here is the complete list of supported cameras. As you can see, the list keeps growing and growing and now includes Hasselblad, Mamiya/Leaf, and PhaseOne Medium Format Digital Backs.

There are two important exceptions:
PSD files saved without the “Maximize Compatibility” setting enabled
Files with dimensions greater than 65,000 pixels per side

As you already know (if you have been following this blog), Lightroom 4 also supports the most popular HDSLR video formats, including MOV, MPG, AVI, and AVCHD.

Keep in mind that the AVCHD support is limited to MTS and M2TS video files. Video editing applications like Adobe Premiere Pro may need the AVCHD file structure to process the files, which can be a pain. Final Cut Pro 7 won’t even take the MTS files without transcoding them first.

This is how the typical AVCHD file structure looks like:
