Pixel Shift on a7r iii

[Jim Sanderson]

I’ve tried the new pixel shift tech in the a7riii on some still lifes. It does show promise. I’ve tried the Sony software and also Photoshop to combine the four pixel shift images. I lean towards the Photoshop method (File>Scripts>Stylize (mean)). Waiting for Death Valley next month to try it on landscapes. What are others thoughts?

Can’t really tell from the jpgs, but the tiffs look nice.

Well Jim, I will say this, no matter what the technology, that's an really awesome shot! Great job on it.

As to the Pixel Shift, I haven't read about that. Is it similar to what Pentax implemented on one of their cameras? The weakness with the Pentax version was shooting outdoors if there was any movement it caused ghosting. Is that still a possibility with this?

 

[Jim Sanderson]

Yes, Jim, similar to the Pentax, although I’m not sure it’s as well implemented. The Pentax assembles the RAW shits in camera while the Sony does not. With the Sony, you either use their new Imaging Edge software or Photoshop to assemble the four RAW shifted exposures. The Sony software is not very good. I hear more choices are on the way.

As far as ghosting, yes, movement causes ghosting in the form of artifacts. I think I’ll end up taking an extra exposure without shift to blend and eliminate artifacts in those areas where there was movement. I’m headed to Death Valley next month and February as the weather dictates and will get a chance to use pixel shift for landscapes in earnest.

That's interesting. I think it has some cool potential to help with images with less noise. It's probably a technology where it has it's certain types of photography where it will excel at.

Yes, the studio still life images with lighting had more detail.
