Sensor shift, Super High Resolution.
 
I was out doing a night photography and I was shooting
https://farm8.staticflickr.com/7924/...2d3c5785_c.jpg
in Manual/LiveComp and then I decided to try Super High Resolution (SHR)
BUT I was dismay at the result.

So I checked, 5 sec was all I needed for that shot.
I set the camera to SHR, Manual to 1s and this is what I got...

Original here

Next question, I can't find the RAW only JPG how is that so?

If that is how the SHR works, than cna I do the same with my milky way shoot? instead of 20, I set it to 4s :eek:

The original looks really great...…………

I think the HR only does give a JPEG, like the other stacked type photos...……

Be interesting to try out a star shot in that mode.....*chr

Edit: PDK42 has corrected this...………..

Yes nice shots and an interesting thought Henry. I'm sure you'll try it out on your upcoming travels. I look forward to the results.

Anyone tried that HR mode in long exposures? Care to comment on the strange findings?

According to my trainer, it's not suppose to work that way. Could it be I am using M and not P,A or S hence the camera cannot compensate and I have to reduce the exposure time manually.

That's sad. Cause I would love to have it in ORF to play with the art filters :(

If it's only in JPG, can't do much post processing :(

One thing I cannot deny, the details up close!!!:eek:

Who needs a FF with that!!!

What did the non HR shot look like up close?

Good question..

this is the crop

Maybe a misrepresentation. :(

Decided to read up on this HR.

Seems that the sensor only move 0.5 of a pixel and it moves 8 times.

needs to be shot at f/4, and by f/5.6, diffraction effects reduce actual resolution below 40mp, while at f/2.8, it is not quite sharp enough.

That looks like quite a difference Henry well shown.

Next to try shoot the milky Way plus how to set it to save in ORF and JPG. According to the Wiki, it's possible. ;)

Hi res does support raw. It saves both a hi res .ORF, and a low test version (the first shot) separately as a .ORI file. If you rename this to. ORF then you can process it as normal. If there are movement artifects in the hi res version, you can use a layer mask in Photoshop to paint in the low res file. Unless the movement is extreme, it hides the artifacts very well.

Re: Sensor shift, Super High Resolution.
 
Here are my findings after studying another photo done with a Panasonic GX8 with a 12-35.

At 5s, the shots are over blown even on a single exposure. It's not the camera to overexpose. Human error.

It can shoot in both ORF and JPG but that is done separately when you select the Sensor Shift High Resolution. You have 4 choices of a huge 40mp with or without ORF, a standard 20mp JPG with ORF or just ORF. By default it's 40mp Jpg. So once you change that, the camera remembers your selection.

As for Astrophotography, the HR may not work as the is capped at ISO 1600. I think the exposure time may be another problem to reduce the earth movement.

Good work Henry, I have tested my setup today, and can confirm I get a Jpeg and and ORF file. I did not realise it was customisable (?).*chr

Re: Sensor shift, Super High Resolution.
 
There is another funny issue.

I have 2 SD used. the camera will not allow ORF only to Slot 1 and 40mp to Slot 2. Did I miss something? :confused:
