HDR - High Dynamic Range / Re: Problems with Noise in Dark Areas
« on: October 17, 2012, 03:04:28 PM »
OK, well maybe its not too dark, maybe the dynamic range isn't large enough.
Hmm I'll have a look at ways to increase the DR I think.

>>FUN!   ;D

Now you tell me!

Issues of HDR aside, I really love the "mood" of your final image. Very nice. The experience you relate here is a great reminder of why shooting multiple exposures and trying different techniques in post is so powerful. You may have started out to use HDR for a challenging exposure situation but had the raw images to go another way in response to feedback. Thanks for sharing.
Thanks. Here's another one that turned out good (IMHO) without HDR.
On here it looks far too dark though, this is still nothing like what it looks like under LR on my monitor.

I hope I don't get banned from this Forum because of this..(I Mean posting non-HDR shots in a HDR Forum).... :-\

Anyway, I'll still be stuck with the noise problem next time I try HDR.

>>insuating you didn't know what you were doing wasn't intentional

I didn't understand it that way. No Problems.

Yes I think it does look far better too.

One of the side effects of HDR, is that the processing can add noise, as it is pushing the exposure in some areas. It is particualrly noticeable if you shoot a silhouette. To be honest, I don't really see the need for HDR when shooting a silhouette, as you would normally just expose for the background and leave the foreground completely blocked out. Also, with such large contrast differences in the transition areas, HDR results in unsightly haloes.
You know, posts like that "usually" upset me, as in "dont do what you are trying to do"! >:(
But I took your advice and from a single shot I managed to achieve what I wanted without any HDR at all,
just with the normal tools in Lightroom. So obviously I'm not upset.
And here's the result. Biggest difference is the almost complete lack of noise and Halo around the tree.
I had 5 bracketed shots so basically went the HDR route without trying alternatives first. 
Thanks very much for the idea.

HDR - High Dynamic Range / Problems with Noise in Dark Areas
« on: October 14, 2012, 03:59:27 AM »
I have read a bit about this problem, but dont really understand why it is happening in some cases. Take the picture below (just a part of it).
That was created from 3 RAW files at -1.5,  -0.5 and +0.5EV.  Its the red pixel noise in the tree that is disturbing. None of the original pictures has that noise. In fact the tree was one of the darkest parts so I expected the information for that part of the picture to be taken from one of the more exposed shots, and
therefore have very low noise.
I processed the HDR in Photomatix. I have not been able to get rid of the noise in PS so I need to make sure it is not created in the HDR process.
Does anyone have any tips how to avoid this problem?
Cheers Brian

What's wrong with just letting the sun be blown out?  When you look at the sun with your eye (which you shouldn't do, so let's say when you look NEAR the sun with your eye) the pupil can't dial down enough anyway, so what you see is 'blown out'. 

You can HDR the rest of the image as you like and it'll look fine, IMO.

Thanks for the answer, I finally got around to trying some options on this, and here is one of the results.
Sun is blown out, as nothing could be rescued there at all anyway. I guess I thought that shooting differently might have helped.

>>Mind you, the JPG looks terribly noisy, the TIFF seems to be OK.
Recreated the JPG directly out of PS instead of LR. I hope that looks better.
Cheers Brian

The sun is going to be blown out no matter what you do. It's a fairly bright light source.
As that is true, even in the least exposed shot, any suggestions how I should have exposed the shot?
As stated I was on spot metering and aimed at the mist, and then bracketed around that value.

Thanks again to everyone that replied.

I see the problem, your raw converter isn't in english!  ;)
Dang, wondered what I was doing it doesn't work then on English photos?

Yeah, this is probably the spot where a grad ND is the only thing that will really get the shot cleanly. You can look into luminance masks if you have Photoshop, as they would help you recover some highlights if they are blown out. You're definitely looking at combining multiple exposures though
Thats a nice technique, I guess its also great for avoiding ghosting created by bracketed shots.
I tried it on another shot and it worked pretty well, I couldn't get the Blur part to work though. Plus the PS action link doesn't work for me at the moment.
Thats a great tip, thanks.

well I thought about HDR, but as the Sun is blown out in the least exposed shot, I was assuming that
I'll not be able to recover anything. Therefore the idea to leave the sky as it is and take the best exposed
land part of the shot.
Unfortunately not shot with a tripod.

driving along early one morning and saw this shot, lots of low mist in the fields. I was hurried as where I parked was not ideal. Anyway I took some bracketed shots, from -2, -1.5, -1, -0.5 and +/-0. But, at F9.5, the sun is blown out in all five shots. I guess using F22 would have helped me.
The -2 shot has loads of noise due to most of it being very under exposed.
I thought about taking the darker parts from one of the better exposed versions to improve it. Anyone got any other ideas how to go about repairing this shot?

What about when shooting? I was using spot and trying to get the mist correct, which seems to have happened OK. I guess a grad ND would probably have helped too.

Cheers Brian

Actually, it's surprising how many birds do hover for short periods, it's only when you try to photograph them in feeding areas, that you notice it. That's one thing with photography, it can show behaviour you would otherwise miss. I've also photographed small birds flying backwards.

I do relax sometimes by just sitting quietly about 3-4 meters from our feeders and observing what is going on.
Sad really!
Still most small birds are too fast and too erratic.

Please read my pleas for help in

AF just does not work for me on the 5D3 with these subjects.

So I grabbed my 7D mounted with a 70-200 f/4 IS and sat on stool on my sister's deck and waited for something to visit her feeders.  She mentioned that hummingbird's frequented them several times a day.

I didn't have much faith that I was going to see one and if I did that the photos would turn out any good.  Well, sure enough one visited after only about 20 minutes.  I took five photos.  Here are three that I was pretty happy with.  I know the composition isn't the greatest, but I think I did a pretty good job at freezing the action in two of them.

They are really pretty birds, aren't they?

Nice shots. How did you focus? I ask because I am trying to capture small birds in flight, on a 5D3. But I guess a
hummingbird will hover a while in some places, different to other small birds that just fly away. What exposure
time did you set to freeze the wings?

Cheers Brian

Here's a new one from yesterday.  I got a little wet getting this shot, but I like the result.

That's great.

I was angling for such a shot yesterday. A sunny stone, all the frogs jumped into
the water when I got close. So I sat down out of sight of them, expecting them to climb back
onto the stone, over the lip and I had my zoom trained on the lip of the rock. After around
30 minutes I gave up.  But I was sat in the sun!

Young Great Tit.

Now if there were a pair of them....   :P

Green? :P

Sorry, those are the only ones that regularly frequent our garden, and that I would be allowed to post on the net!

Actually I happen to have a "Great Tit" pin from the RSPB that I wear on my Fleece.
We were in a Pub, and the wife asked what I prefered, answer "Great tits", and she bought me it.
I still dont think she has caught on (Its the last vestiges of resistance after 32 years of marriage).
