Expert Raw: Astrophotography. A real life experience and possible improvements

[Members_cUiO5xF]

Hi All

I love astrophotography. That's the main reason I've had my S21 Ultra and later I traded to a S22 Ultra. Before consider changing to a newer phone I need t make sure I'll get what I need and no less. That is why I have not changed to S23, S24...Etc.

My hope is Samsung can learn from this experience and improve it in the near future

Expert Raw: Astrophotography mode is amazing... but there are many details that make it prone to fail and is hard to understand why is not working right.

When doing Astrophotography the regular  AUTO focusing method is not worth it.... It'll most likely fail , but nobody says that! ... IMHO is better to do it in Manual. But the method of adjusting the focus by the slider is not good because is not precise!. I feel it would be better instead of 1 digit precision (FI 0.7) to have  2 digits precision (FI 0.77), and being able to save it and keep it for future!

I have taken Astrophotography out of the Astrophotography mode, just longer exposures up to 30 secs. But when looking at the photos you can see "artifacts"... those lines around that make me think "what...why ?". It is strange. Please look for yourself in the photos of the comet I'm attaching. 

I hope you see the photos I'm attaching. The good one is 4 minutes long this is using Astrophotography mode. The other photo with "artifacts" is 30 seconds

The lines are probably just the way your phone processes the picture and the presets of said processing. I've heard expert raw for astrophotography has presets that pretty much edit the photo for you while regular modes only have a few edits. I hope that makes sense but I'll drop my expert raw and regular pro mode photos of the stars and let you decide. They are on my S24 Ultra btw and the expert raw is the one that shows the milky way in the bottom left while the pro mode is brighter in the middle

I need to try this...probably need to read up and get some coaching too.

Download good lock then get the camera assistant extension and you should get a new mode in the camera app called expert raw. Click astrophotography mode and choose short, medium, or long and it'll take a picture for 2 minutes to 15 and the high exposure takes an amazing photo
