If anyone ever wondered what jpeg artifacts really look like, here's a good example. Cellphone shot out my front door this morning and though I had set to dng (raw) format, but somehow missed it and ended up with a jpeg image. When downloaded, the sky artifacts were noticeable so for fun I through the image in Aurora HDR and pumped em up!

Pretty pic. When you shot that jpeg how large was your sensor?

I remember a couple of jpg's from my bridge camera that showed sky artifacts - probably made worse by my processing.

When did cell phones start offering raw? I don't have a smart phone so haven't paid attention

I believe Samsung started about 3-4 years ago with dng as an option. My S8 is 2 years old and defaults to jpeg so I have to remember to switch to dng every time. Not sure about other phones.

Linda, there are a some Phone apps that will allow you to shoot RAW/TIFF images on the IPhone
I think some of the them work with Androids.
Camera Pro
ProCam
Moment app

These app allow you manual controls for ISO, Shutter speed, etc. with some interesting results.

You like the layered jpeg artifacts or am I missing something?

I like the way the picture turned out after you had done HDR on it as I presumed that was the final image...

Hmm, well, I'm glad you like it...... jpeg artifacts, sometimes called banding, is normally something we try and avoid. Maybe I'll have to do more like this, eh? 😉

I liked it from the start. Sometimes you spend hours trying to get a desired effect in pp and never quite succeed, sometimes you get artifacts that totally ruin a picture and sometimes the artifacts add to the overall composition. Tone down the brightness a bunch and I think you have a keeper.

I might be missing something here but if a highlight is blown, it's not salvageable regardless of the format it was taken in. If you blow out a highlight shooting in RAW, there is no detail captured and no amount of post processing is going to get it back.

Steady, MRJ. A sincere comment and/or question deserves more respect than shouting and five exclamation points. If you're not up to providing a thoughtful response that will aid in learning, then please move back to main discussion forum.

Perhaps you simply don't understand my kind of humor Ma'am.....😉
