HDRI tutorial

“HDRI tutorial ” by Joshua Murphy
The settings for the Lens blur are as follows:

Radius 15-25
Blade Curvature 15-20
Rotation 60-100
Leave everything else at the default value. Now you should have something like I do below.

Next, what you want to do is go to File, select Automate, and then select Merge to HDR.

When you select that, a dialog box will come up and ask you to browse and find the source files. Browse to where you saved the 1.psd – 7.psd and select all of them. It will look like this.

Hit OK. Once you do this, all of the files that you have previously adjusted will popup, and then merge into one. This may take a few seconds. When this is done, a dialog box for the Manually Set EV will come up. In this dialog box, you will manually set the Exposure Value for each of the images that you created earlier. For image 1 you will set the EV( exposure value) to 3, then for image 2, set the EV at 2, for image 3;1, for image 4;0, for image 5;-1, for image 6;-2, and finally for image 7;-3. Your final image should look something like this:

Once you have your final image, save it out as .png, which helps the compression of the image. If you were to save it out as .jpg, it may become a bit pixilated. Once you have done that, all that is left is to apply it to your chosen 3d application. I am using 3DS Max 9, if you are as well, open your scene, go under the Rendering tab, select Environment, and apply it to the Environment Map slot. Make sure that the Use Map check box is selected. Then render. This is a good way of making your own HDRI map out of virtually any image. I use this method a lot for vehicle renderings.
