Hi guys how’s it hanging.

Anyway back on topic.

So the way your camera sees the world and the way you see it always means that blacks and blues are to much even if you think the photo looks great.

HDR works by the camera taking 3 shots of different exposures and then blending them via software to present an image hopefully as you would see it.

See x2 photos. It should be a no brainer to figure which image is HDR.

And

Its the same shot my camera makes x2 copies with and without HDR.

Oh, I find I cannot use HDR all the time as HDR is programmable and so it only works about 70% of the time.

Don’t use HDR all the time, or you could end up with something like this:

TBH I don’t bother with HDR on my LG G5. Or RAW for that matter. But I’m an opportunistic point and shoot person. Can’t be arsed messing about.

The 3 cameras are that good, what they don’t get right Google will! Mostly.

I was messing around at the bus station the other night. Downloaded a couple of more granular camera apps on to my phone.

It was really dark being midnight, and I was sure I could do better than the standard camera. On the pixel it’s always in hdr + mode. In this camera it doesn’t slow the shot down.

On the phone I just couldn’t tell the diffence. When you are I views them at home on the screen, all I manage to do was make the shots worse.

As I have no idea how to upload a photo here, I’ll like to the photos, also wont get compressed, as you’d never see the diffence. The first photo is the standered pixel camera app, and the other three pics are from two “pro” apps that’s let to mess with the settings.

I won’t be using them again.

All the pics are not great, as it was a challenging shot. Very dark with bright lights in the distance.

In the past my phones have had to wait while it take the 3 pics, early days it would physically take 3 one after the other, later it would take them all at the same time, but still there would be a time penalty. The nexus 6p had a buffer issue if you took to many to quickly. But the pixel is instant, and there must be a buffer point, but on a local day out I took many pictures, and never got slowed down.

Last year in the Bernabeu, I forgot the phone camera and was amazed on how good the 6P performed, but did get the msg a fair few time, “you can’t take more, untill I finished processing”

Nice pics if you’d like to see them (and the nou camp), all taken on a phone, in its auto mode.

The pixel has the same Camera set up, takes almost identical snaps, but is just quicker and no buffering.

Them pics are ment to look that way. You can’t really make pics like thst from a phone. You’d need an dslr, taking minimum of 5 exposures, half a stop been each. Bit probably 7. Then you need to edit the file rap out of them in first photoshop then in port them Photomatrix, then back to PS.

I’m a fan of Proper HDR photographs, but not to over done. But it depends on what the subject is.

HDR on a phone is very subtle. Mainly because the lens just can’t take a really wide range of detail. It’s just just to compensate for the crappier camera. Though phones (mod range up) now do take more than good enough shots for normal non photo nerd people.

My dslr early comes out it’s bag these days. Just for special occasions, etc.

I thought this a good as place than ever for this. Given the pixel uses hdr as default.

Ten to midnight, I was getting in the car to go out and pic my girl up, and the sun still hadn’t fully set.

I want sure how the forum software would handle res, so below is a link to the original. (no flash), and just point and click, all in auto.

Check out the time stamp on the picture via a third link, then press info it time and location should be there.

West coast, so we get the last of the sun for the uk.

An hour later when I got home it was pitch black.

I was more amazed on how well the phone captures it. It was real dark where I was, and not alot of noise in the pic.
