Photo Processing HDR in Photoshop CS4

July 20th, 2011

After reading the tips on taking raw HDR image, it is time you began processing these photos into HDR photos “cooked” using Photoshop. Here are the steps:

1. Open the Photoshop application. Click: File> Automate> Merge to HDR> Click on Browse.

2. Select the files that have been prepared (Ctrl + click: Win; Command + Click: Mac), check the option Attempt to Automatically Align Source Images, and then click OK.

3. You will be taken to HDR dialog box menu, this time the combined result will not satisfy.

4. HDR dialog boxed, there is only one setting that needs to be done is setting the white point at the top right corner of the histogram. If necessary, slide the slider below the histogram until you are satisfied with the look of a picture and click OK.

5. We will be taken to the main menu Photoshop, and images look uglier. Do not worry, it’s because the images are in 32 bit mode which are beyond the ability of our monitors, we will change it.

6. Click Image> Mode> select 8-bit/channels or 16-bit/channels (if your computer is quite slow, I recommend select 8-bit).

7. Dialog box will pop up again.

8. Boxed select the following settings:

Method: Local Adaptation
Click on the small symbol to the left writing Toning Curve and Histogram
It would appear that the curve wills we play:
Click on the top right corner of the histogram, and then slide it to the left until near the right end of the histogram
Click the bottom left corner of the histogram, then slide it to the right until near the left end of the histogram
Set the Radius to 2 px, the setting becomes as below:
Click OK

9. Save the image with Ctrl – S (win) or Command – S (Mac) or click File> Save As.

10. When the Save As dialog box appears, name the file and change the format from the PSD to TIFF and then click OK.

Easy Steps to Setting Up HDR Photos

July 5th, 2011

Photo HDR (High Dynamic Range) is a photograph obtained by combining several images with varying tones so as to produce an image that has particularly tonal range beyond the original capabilities of the camera. Before it can be processed, we have to make some raw images that have a different exposure, the number of images required is between three to five pieces. Here are practical steps:

1. Because we will combine multiple photos at once, use a tripod so that the results are sharp and no ghosting

2. Set the camera in aperture priority mode (A or Av), with this mode you select the aperture and the camera was the one who determines the shutter speed

3. Set focus on the position of the manual focusing. Try some snap to determine the focus in autofocus mode, after we set the focus, change the manual focusing mode

4. Set automatic bracketing on the camera to produce 3, 5 or 7 fruit photos with shutter speed varies (Nikon & Canon, for other cameras please see the manual):

Nikon SLR:

Click on the Fn key (bottom position in advance)
Rotate the command dial behind the camera until we see a sign on the LCD above bracketing
Select five bracketing (or 3, 5, 7 or to taste)
Change position on a continuous release mode high speed

Canon SLR:

Click and hold the Mode button and AF.Drive to activate bracketing
Set of 5 in the Custom Functions menu (or 3, 5 or 7, according to taste)
Set the camera in burst mode
Begin taking exposure
For processing we are able to use special software such as Photomatix Pro for HDR – (free demo version) or do it in Photoshop
