Empty Photo Asset Results After Save

This appears to be new behavior, and wanted to confirm this is a bug. To reproduce: 1) Enable limited photo library permissions in your app. 2) Don't select any photos. 3) In your app, save a Photo. 4) In the performChanges callback handler, perform a fetch using the placeholder asset ID. Previously, it would return the asset that was just saved. Now it returns an empty array. However, the photo library observer seems to correctly fire, with the asset included, as expected. I've filed FB7774980 to track this.

CIRawFilter And Values Greater Than 1.0

I'm currently trying to extract the pure linear data from a decoded RAW, without any sort of tone curve. I'm using the `linearSpaceFilter` key in CIRawFilter, and finding that in scenes with significant dynamic range, the brighter values (e.g. clouds) are greater than 1.5 in the linear kernel.Is there an explanation for this behavior? My current theory is that CIRawFilter picks a default ramp that displays pleasing results on a SDR display, similar to why it has a default boost curve.What does this exposure ramp look like?

MultiCam RAW

It's my understanding that the only way to configure AVCaptureSession for RAW is to set the `.photo` preset. However, AVCaptureMultiCamCapture appears to not support any presets. Can any Apple folks confirm MultiCam RAW is not possible at this time?
