Talk HDR......

[andy_fozzy]

ive found when it comes to exporting my raw files to multiple exposures
and importing them in photomatix
they look really really really noisy and get weird oversaturated colours
does anyone know why that is??
even if the pictures been taken with a low iso, 100 in some cases??

A noise removal program :shrug:
I get noise on EVERY HDR I do, so I run them through Noiseware Community edition (free!) Yes it's a pain, but gotta be done.....

Keep the shots and posts coming guys. Loving this thread

See - it's this glow (sorry, Andy - this is not a criticism of either your work, or you, but rather of the discourse of HDR) that I think detracts from HDR:

You're quite right.
I'm still very new to HDR, and still trying to figure out how to minimize this glow.
It drives me mad too :bang:

Much of the HDR effect can be gained far more efficiently - and controlled - by simply messing about with the Shadow & Highlight options in PShop.

Indeed. And there's also the contrast masking option.....
Works very well.
This shot didn't look that good with HDR. Contrast masking looked 100% better.

Here's the HDR version:

It's all a matter of personal choice of course. Personally, I love HDR - even the so-called 'overcooked' ones.

I love HDR for rescuing rainy days out that might have been wasted otherwise. Its better than coming away with nothing

Overdone??

Not at all


I use Topaz Adjust:

Nice to see this subject is running nicly.With some great images..

I use Noiseware Community free edition, works well, but understand the Pro is much better, i suspect it would be as its quite pricy.

I wonder if anyone has used the noise reduction plugin for PSCS2?. thought about having ago with that as well...

What is the difference between HDRi and 'tone mapping'?

 

[Trixster]

I always try and keep iso as low as possible when taking exposures for HDR in order to minimise noise.

 

[tommo]

I've read the magazines, read the online instructions, but do you think I can make a good image? Can 'eck as like. Maybe I need to reduce the ISO.

I think the best HDr images are thos where you don't know its been done, like the bee above

Good question. I've no idea!!

Not thought about the plugin option.
Is it much cheaper?

I love the first shot it's one thing HDR works really really well for. The second shot I think has great potential but at the moment the ground is a bit to vibrant for me. What I usually do is take the HDR'd shot like you have there put it into photoshop then overlay the original back on it then play with the blending modes.

overlay or softlight gives a very contrasty dark colours look, not really suitable for landscapes but works well for some subjects.

Colour works very well for a lot of shots, basically it takes the tones from the HDR and applies the normal colours so you get the nice hdr tones with the more subtle colours that came directly off the camera. I use this a lot with landscapes.

Lumination, this takes the tones of the original then uses the colour from the HDR version.

Adjust the opacity to alter the strength of the effect.

Much of the HDR effect can be gained far more efficiently - and controlled - by simply messing about with the Shadow & Highlight options in PShop.

As contrast masking was mentioned, I use it as well as HDR'ing sometimes too. I would quite often have a HDR image with a copy of the 0EV shot over it then a contrast mask of the 0EV shot above that again to help make subtle adjustments to the image.

What kind of issues are you having with HDR tommo?
As mentioned, you'll need as low an ISO as possible, but for some reason, HDR shots of my PC always come out a bit noisy.
Try the Noiseware community edition, it's free and easy!

High dynamic range imaging
In image processing, computer graphics, and photography, high dynamic range imaging (HDRI or just HDR) is a set of techniques that allows a greater dynamic range of luminances between light and dark areas of a scene than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.

wikipedia

Tone mapping
Tone mapping is a technique used in image processing and computer graphics to map a set of colours to another; often to approximate the appearance of high dynamic range images in media with a more limited dynamic range. Print-outs, CRT or LCD monitors, and projectors all have a limited dynamic range which is inadequate to reproduce the full range of light intensities present in natural scenes. Essentially, tone mapping addresses the problem of strong contrast reduction from the scene values (radiance) to the displayable range while preserving the image details and color appearance important to appreciate the original scene content.

It really does amaze me how anybody can NOT like HDR.

The problem is (as was stated earlier) that you only know it's HDR if it's obvious. If it's done well, and subtley, you can't tell and don't know.

Therefore HDR gets a name for itself by being associated with overprocessed graphic images.

I don't do it myself and never will as I use 100% film which has greater dynamic range. I will use ND grad filters though to tame down a bright sky where necessary. This is just as valid and is really the same thing except it is being corrected in camera rather than post processed.



Steve.

I find the 'overcooked' ones remind me of Console/computer games, buildings for example i find have tons of detail but look flat.
But, there are some STUNNING HDR's out there, and i'd like to give it a go myself. *finds bracketing option on my NV8*

 

[groovyf]

This is my first foray into HDR. These are the first pictures I've done using Photomatix - a couple of weeks ago.

 

[Davec223]

I downloaded photomatrix a while back but realy have not had much time to play with it. I did have a quick play when I first got it and came up with this.

And this is it before HDR, I used one raw and a few converstions ( can not remember how many at this moment)

I really like it but I am sure their are plenty of people that think it is way overcooked. As loads of people have said it is all a matter of personal choice and I see it as another tool in the box to get the shot that you want.

 

[theMusicMan]

Nope, not overcooked at all Dave, in fact I think it has significantly enhanced the final image. Excellent processing I'd say.

 

[melevo]

this is my attempt from the TP meet at whitby last year

 

[melevo]

and this is my other attempt from Beamish nearly 1 1/2 years ago, but i would not say these are great but they are my "i will have a go"

 

[Forbiddenbiker]

Love the grave yard shot, hdr and stone works so well every time I think.

This is my first foray into HDR. These are the first pictures I've done using Photomatix - a couple of weeks ago.

Very nicely done too. Love the view point.
