This is a basic, standard, step by step tutorial of how to make an HDR Image.(Note: this tutorial is based on building an HDR image from 7 different shots.
The materials for this process are as follows:
- Digital Camera (Obvious, but hey you never know :) )
- Tripod
- Photomatix (used for Generating HDR and Tone Mapping) You can buy it with 15% discount here
- Photoshop CS2. (But for this tutorial any version of Photoshop will do. We'll be using it for retouching only)
Hardware:
Software:
Ok, let's get going!
Taking the pictures:
Put your camera in the tripod. Place it firmly because you will have to touch the camera to change the speed and this can make you move it, and then, well you won't be able to get the HDR you were hoping for. After selecting the subject you wish to shoot, prepare everything as if you were only going to take one picture. Prepare it to your taste or what ever is you want to accomplish. Set your primary exposure and speed. We are going to call this master setting 0. After this is complete and you have everything set up you are going to take, let's say, 7 pictures:
3 pictures up from 0 and 3 pictures down.
Dude what do you mean? Don't panic is quite easy: If the settings for picture 0 is: 1/125 and f/4.5 The settings for the remaining pictures are as follows:
- Picture +3: 1/250 f/4.5
- Picture +2: 1/200 f/4.5
- Picture +1: 1/160 f/4.5
- Picture 0: 1/125 f/4.5 (YOUR MASTER SETTING)
- Picture -1: 1/100 f/4.5
- Picture -2: 1/80 f/4.5
- Picture -3: 1/60 f/4.5
You may have noticed that the F/ stays the same. This is quite simple: if that value changes also will you Depth of Field which will cause your focus to change also. Now that you have taken all your pictures is time to go and kick some Photomatix but! Ok, so you got to your computer, opened up Photomatix, and oh well you have no idea what to do. No problem because this part of the process has little pictures in it, so you wont have any excuse not to make HDR pictures!
Photomatix:
Open Photomatix and look for the HDRI tab. Click on it. After you will see GENERATE HDR. Go ahead click some more.
When you do that something like this comes up:
Now you click on the BROWSE button and select the pictures you want:
After you you click the SELECT button a screen like this come along:
Ok. Now your pictures are selected and you click OK. Now you have to choices: to Align Input Images or not to let the software do it. I personally always let the software do it. Is up to you:
Now you'll get this screen. Depending on you computer memory this may take a while, but not to long. I've notice that when one of the picture is to dark or to bright, in Auto Align, Photomatix has a hard time aligning the images. I usually cancel and deselect the image I think is causing the problem:
If everything is ok, this should come up:
After Photomatix is done, it shows you your new Generated HDR Image:
But you want it like those cool ones out there! Wait, there's more: ToneMapping!
Now you go to the HDRI tab and select Tone Mapping. Here is where the fun begins!
The first thing you may notice is the difference in the picture. Here you have 7 important options:
- Luminosity
- Strength
- Color Saturation
- White Clip
- Black Clip
- Smoothing
- Micro Contrast
