It could be your pixel dimensions that are at fault.
Maximum of 65,000 pixels along the longest edge, and no more than 512 megapixels (not megabytes).
What is the exact error message, letter for letter, and exactly when does it appear?
LR imposes the following requirements:
- All images must be no more than 65,000 pixels on a side.
- The total number of pixels (width x height) must be less than 512 million (e.g. 22,627 x 22,627).
- The PSD must have bit-depth 8 or 16, not 32.
- PSDs with multiple layers must have been first saved with the Maximize PSD and PSB File Compatibility option turned on. (Note that turning on the option after the file was first saved will have no effect, even if you re-save the file.)
Ahh, thats it then, my file is 18,562 x 28,993 (538 million I think?)
I guess then the only solution is to down rez?
BTW How does one turn on PSB file compatibility, does that mean it would then be readable in Lightroom?
No, it doesn't. Maximize compatibility must be turned on in any case. But your image has too many pixels, and LR won't import it, period.
Yes, I understand the pixel size limitation after you and johnrellis mentioned that but I was just interested to understand where is the option johnrellis mentioned "PSb file compatibility option turned on"?
Meaning can Lightroom view a PSB file that is under 512 million if such an option exists? Thats the question.
Maximize PSD and PSB File Compatibility must be turned on only for files that have multiple layers. If your file has just one layer, that it's not necessary.
In Photoshop, go to Preferences > File Handling and set Maximize PSD and PSB File Compatibility to Always. If you have PSDs with multiple layers that were saved before enabling that option, you'll have to do File > Save As to save a copy to get compatibility enabled in each such file. (File > Save won't work.)
Ahh, thanks for the clear reply, turns out I had it already set that way.
