Digital Photo Professional 4, HDR Compositing Slight Cropping Issue

[photoguy4]

I'm noticing that a slight cropping occurs when creating HDR images out of Digital Photo Professional 4. When HDR images are brought back into photoshop and stacked on top of original, bracketed exposures the HDR is clearly scaled in about 5%. Is there a way to disable this cropping? I've also noticed a different lens correction is applied vs the original bracketed base images. I'm trying to use this function for an architectural workflow with layers in PS and need to solve. 

"Align" function is not checked.

When you open the original bracketed images in Photoshop, are you opening the RAW image or the JPG?

Lens corrections are different in DPP and Photoshop

Could you please describe your work flow, from camera to customer?  It sounds like you are starting in PS.  And then you make a round trip to DPP and back to PS?

Thanks for the reply! Opening original RAW images with lens correction auto applied from EOS R5 (in camera).

Thanks Waddizle. Bracket captured on R5 with lens correction profile auto applied in camera (Eos R14-35mm)-> launch DPP4 with bracket import-> Merge using HDR function-> bring HDR Jpeg into PS-> bring RAW frame from bracket into PS as a layer on top of DPP4 HDR Jpeg. 

It's at that point where I notice both a different lens correction and the cropping.

The JPG created in DPP will have the Canon lens profile corrections applied since it was switched on in the camera. Photoshop uses Adobe Camera RAW to process the RAW image and can be set to apply Adobe's lens corrections or none at all. It is very possible that the Canon and Adobe lens corrections are different, and this would account for the difference in the two images when layered on top of each other.

Any way to toggle lens correction off within DPP?

You could see if the boxes are checked in DPP and if so uncheck/use the back arrow.

 If you are recording RAW images and using DPP it might be better to turn off all in-camera corrections. DPP frequently has stronger corrections and file saving will be quicker in-camera since there is no processing.
