What to post on this board.

1. HDR (High Dynamic Range) photos – usually generated from 3 or more images.

2. Pseuo-HDR or single images which have been tonemapped or modified to emulate HDR are also suitable.

3. Please do not post non-HDR images unless you want to illustrate part of your process or make a point to readers of your thread.

4. Only make links to your images under exceptional circumstances. Follow the Posting Images Tutorial if you are in doubt. A list of free hosts can bee found here: Image Hosts that do not compress your photos

How to Get Started
Search the internet and you will find numerous web sites which offer advice on this
topic. However, most of the reviews are out of date, some go back to 2008 or earlier.
Some reviews contain recycled phrases from different web sites and don't even mention
the most up to date software. As the HDR applications market is advancing and expanding
rapidly, the consensus on this forum is to download two or more of those listed below
and try the free trials for yourself. Features to look out for are:

Graphic Interface - is it too simple or too complex? After watching a tutorial, can you understand it?
Image Alignment - Does it work for you? if you want to take hand-held shots, this is very important.
Lightroom/Photoshop - if you use either of these, is there an an integral interface or plugin?
Thumbnail Presets - these are very useful for beginners. Do they cover your requirements?
The Bottom Line - Do you like the output? Post a few tests on this forum and ask if other Camels like them.

Pre-Processing

Chromatic aberrations (CA) are common color-fringing effects caused by a lenses inability to focus multiple colors to the same point. For example, the resulting images from each light spectrum is in focus, but each image is a slightly different size so that the colors to not align 100% correctly. If you have CA in your original images, it will be 10 times worse after HDR processing. Follow these tutorials and find out how to remove CA in before you start any HDR processing.

or
Chromatic Aberration in Lightroom 5N.B.
CA can also be removed with DxO Optics Pro

If you still have CA after processing, you can use these methods in Photoshop to remove it.

Noise Reduction is also advised before process. See Noise below.

Correcting White Balance
If you get color casts or the colors just don't look right after a trial HDR
process, you probably need to adjust your White Balance (WB) before you merge
your images. It is much easier and more accurate to do this in your RAW converter
than it is after the HDR merge. Any uncorrected cast that is in your originals may
generate even more of an issue as you go through the merge and tonemap process.
If you have used a high ISO value, it may be advantageous to apply a small
amount of noise reduction before exporting as 16bit TIFFs and do your merge.
RAW file White balance adjustment tutorials using Adobe Camera Raw or DxO Optics Pro are listed below.

If you do not have listed above, you can use Bibble, Capture One, DPP (Canon), Silkypix, SilverFast, or UFraw (free) for
adjusting White Balance.

Post Processing (PP)

Web quote, “Alright everyone, this is it. This is where the overwhelming majority of
HDR photographers produce over-saturated, haloed, noisy, over-detailed, messes of
HDR imagery. Poor post processing is what gives HDR a bad name and causes people
to hate HDR for how psychedelic it looks. Post processing is the hardest and most
important part of high dynamic range photography.”

James Brandon, digital-photography-school.com (2010)

This edict is very important but should be qualified slightly. Currently, in 2013, a new
generation of HDR processing software has emerged which, with the exception of resizing,
is capable of making web-ready images. However, some simple post processing steps will
usually improve them.

A Google search for HDR Post Processing or Post Processing Workflow will find more
tutorials than you can digest in a week. Here are a few to get you started.

Noise
One byproduct of HDR processing is noise. This is the graininess that appears
typically in the blue channels, as well as in darker, shadow areas. Most HDR
processors denoise your RAW files before tonemapping but they do not eliminate
noise created by the tonemapping process. Some HDR software is noise prone while
others generate much cleaner images. Whatever HDR product you use, denoising
should be should always be the first step in your post processing process.

The best advice on both pre- and post-processing noise reduction can be found here: The Three Rules of Noise Reduction.

N.B. If you pre-process your RAW images in order to make lens distortion corrections,
always denoise them before saving as TIF files for your HDR processing.

All good photo-editors have a denoising facility but the specialized denoising plugins
are more sophisticated and more effective. The most commonly used denoise plugins are:

Neat Image
nik Dfine 2
Noise Ninja
Noiseware Pro and Noiseware Community Edition (free)
Topaz DeNoise

A tutorial for most of these products can be found here: Photo Noise Reduction Tutorial
Noiseware Pro hardly needs a tutorial as it has an intuitive interface.

Odds and Ends

Two often forgotten PPs on this forum are perspective correction and horizon levelling.
If you have Windows there is a free utility, ShiftN, which will do both these corrections
for you with one mouse click! Mac users will have to use a traditional method such as:

Editing Mermbers images.
There is an option under each member’s avatar indicating whether or not they allow
editing of their photos. Members should enable this so that a “No”, "Yes" or “Ask First”
appears. Please only edit those who have a "YES" below their avatar and do not remove
the original watermark/logo under any circumstances.
N.B. When editing other members’ images, we strongly encourage you to use the
upload or attach options within a thread rather than putting the reworked image in
your gallery, where it could be mistaken for your original work.

Enabling the editing “Yes” option by new HDR workers is highly recommended as you
are much more likely to receive feed-back from other Camels in the form of a tweaked
image and step by step advice. This will help you to tackle the steep initial learning
curve that is inherent in HDR.

To enable editing, follow this sequence:
Quick Links > Edit Profile > pan down to Additional Information > Check the Yes button

Once photography enters your bloodstream, it is like a disease.

Software: Too numerous to list but my most used utility is ShiftN for perspective correction

Gear: Canon G12, no tripod, no lenses, no flash, no remote, no cases or bags!
