There are several steps to HDR photography. We’ll cover the basics first; what HDR is, when you’d likely want to use it, equipment, software, the best camera settings to get the best results, and post processing.
HDR stands for High Dynamic Range. Have you ever found an interesting scene, photographed it and only later discovered when downloading the picture from your camera that the image has come out a bit flat and doesn’t look at all how you remembered it? HDR compensates for this. The human eye and brain tend to pic up more light and is able to correctly interpret that light better than your camera. To give you a little perspective, the human eye can see 11 stops of light, where your camera can only pic up 3 stops.
With HDR you can compensate for this and produce photos that reflect what you actually saw more accurately. This is especially helpful when confronted with a scene where there are different exposure levels that cause part of the image to be either over or under exposed. For example, id you have taken a picture of a scene where the ground and buildings are properly exposed but the sky is complete over exposed and washed out.
There are two major steps in HDR photography, the actual taking of the photo, and the post processing. We will deal with taking the picture in this tutorial, and in the follow up tutorial we will cover post processing.
First off you need the right camera equipment:
These three I would consider to be completely optional and you have to make a judgement call on whether the HDR you are creating needs it or if it would be overkill.
So here we get to the action. When taking the shot in HDR you are actually taking 3 shots. That is our baseline, you can take more and that is up to your personal preferences and what the situation ideally calls for as well as what your camera and equipment is capable of delivering. Nikons have the capability of 5 bracketed shots where a Canon can do 3.
-so glad you asked. On your camera (if you are using a DSLR) you can set it to not only take a particular exposure, but to take more shots straight away at an exposure adjusted setting. The most common being -2, 0, +2. This is bracketing; You press the shutter once, and three images are taken at these different exposure levels. You can choose though so if you really wanted you could do -3, -1, +1 or -1,0,+1. Whatever, its up to you. I have so far found that -2,0,+2 is a robust combination and it is what most HDR photographers recommend. Well, that’s a half truth.. It depends on your camera’s capabilities. For me that’s 3 bracketed exposures. Many Nikons can do 5 and with software you can make it as much as you want. I manually did 9 once but the thing is, 3 - 5 is generally enough. 5 is better than 3 usually.
Here are the camera settings you should use for best results:
Now you're ready to shoot! This is what I do, I use a remote trigger and listen as my camera takes three shots in quick succession, each one taking a different exposure time depending on the bracket settings. I might take another for good luck and move on to my next planned shot.
Now comes the part where you turn your shots into an HDR. There are many techniques and different software packages that will help you accomplish this as mentioned above. As well as many different levels to editing. I'll just share with you my workflow:
First off I import my photos into lightroom..
Once you export you get a menu screen that asks you particular import questions. Here are the settings I use:
Next you get the ghosting screen, we skip that. Then the program does its magic and applies the HDR algorithms to the 3 exposures, rubs some voodoo on it and then combines them.
We still have work to do. So the 3 exposures are combined and now we have to play with the settings to get the look we want. Now this greatly depends on individual tastes and many who are new to HDR often go for the overcooked look. I'm guilty there too.. What is that you ask? Its when you do an HDR with lots and lots of colour and deep saturation and bring out every insane detail. It becomes sensory overload and is not very pleasing to the eye. I'm not going to show you that, if you want to see it then do a google image search for the term "overcooked hdr" and try not to get a migrane.
So for this image it's a bit dark and the colours are a bit dull. So what I am going to do is work to brighten up the image and boost the saturation a little. Now with HDR the only thing you can really do is experiment with the sliders until you get the look you want (or opt for one of the presets). As you get to know what each slider does to effect the image your experimentation will go a little more quickly.
General rules I go by are that I keep the strength in the high 90s, and saturation between 50 - 75. You rarely need go higher and often with HDR you might want to consider lowering the saturation to prevent the image from looks too unrealistic (unless that's what you want).
To brighten the image I had to boost the gamma, which I did until it reached a nice brightness level, and increased the smooth highlights slightly. All the other settings remained the same (they were saved from before).
That's better! I can see some dust spots and marks in the shot but that can be fixed when we go back to lightroom. Which is what I do next, I go to lightroom and make some final edits to the image, including cleaning off dust spots, adjusting sharpness etc.... let's go! Click the Save and re-import button and head back to lightroom. Sometimes it takes a while to reappear but when it does you go into developer mode.
So here we are, and I can see I just need to make a few tiny adjustments. I've been lucky with this one so all I do is up the exposure just a little, lower the highlights a tad, up the shadows and the clarity as seen in the settings to the right here:
Now all that's left is to take out the dust spots and we are done! I won't show that here but there are plenty of instructions online on what to do. Chances are, if you have 'em in your images, then you already know how to fix them! ;)
So that's all I do with an HDR to get the shots I get and it should be a good starting point to get you going. Remember, this is just my workflow for HDRs. There are many different ways to get the same, better or just different results. Find an HDR program that's comfortable to you and have fun. I use photomatix because I've been using it a long time, it's familiar, the controls are simple and it gets me the look I am after. Anyway, have fun and don't forget to share your shots with us!
This tutorial is an extension of a previous tutorial I wrote on my old wordpress blog. The original (and incomplete) tutorial is here: HDR TUTORIAL PART 1 – BEGINNERS HDR.
I finally decided it was time to re-write, update and expand this old post and share it with steemit.
Thanks for Looking.
