Lightroom 4.4, Photoshop CS6, Win7. I imported three photos from my Sony a55 into LR, converted the RAW files to DNG, each about 17MB. I selected all three then chose Edit In > Merge to HDR Pro. After they merged I changed it to 32-bit and selected OK. Then saved the file and went back to LR. I saw the PSD but it had this error, "Lightroom has encontered a problem reading this photo." However, if I save the file as a TIFF then import the file I can edit it all I want.
Both PSD and TIFF are 166MB.
Why do I get this error with the PSD in LR but not the TIFF? The colors with the TIFF seem off, fake, it doesn't look real.
