EV @ -.7, Fuji S5 Pro on Tripod, Aperture Priority, f11, 5 frame auto bracketing mode set at 1 f-stop apart per frame. Cable release. Processed in Photomatix

and some minor Photoshop/CS4 work (lens corrections [e.g., tilt & shift] and my reflection removed from dresser mirror). 100% natural lighting!

As captured at the scene (raw) Single file conversion to HDR and tone-mapping using Photomatix Pro Detail Enhancer Application. Minor – very

minor – finish work in PS/CS4.

The Journey…

1. View output differently.2. A few tools of the trade.3. Some great software.4. Willing to experiment5. Time to have some FUN!6. Understand the Real Benefits of HDRi

Page 23: Hdr magic

CREATIVITY IS WHAT GIVES BRANDS TRACTION IN THE MARKETPLACE!

I.E., Where the rubber meets the road!

The Physical Stuff

• Camera capable of raw file capture preferred

• Lens of your choice

• Polarizing filter (optional)

• Stable tripod

• Cable release

• Memory cards

• Spare batteries

• Flashlight for light painting

• Fill flash (optional)

• HDR software (Photomatix Pro® preferred)

• Computer (for post)

• Card reader or USB tethering cable

• Processing software (e.g., Photoshop, PS Elements, etc.)

Page 25: Hdr magic

Software Available

• Photomatix Pro (The Best) for Mac or Win - $99• Nik’s NEW HDR EFEX Pro ($179)• Hydra (up to 4 frames) aprox: $79• Dynamic Photo HDR (some “cool” effects) - $55 ($75

with PS4 plugins added for 8bit RGB editing)• Photoshpere (Mac only – freeware)• Many more can be found at:

Page 26: Hdr magic

Camera Settings• Set to raw capture• Color Space (default setting) @ sRGB.• Turn off enhancements (I.e., no sharpening)• Establish a “set” white balance (I prefer Auto)• On manual/auto bracketing: Set for TV/Speed

(shutter speed changes and not aperture)• Experience & Testing Reveal: Set EV to -.3 (default),• Auto bracket: 3 to 9 depending on camera @ 1 EV

stop apart min.

Page 27: Hdr magic

Camera Settings• Typical AB is 5 frames at 1 EV apart per (Nikon)• On most Canon (some Nikon) set for max of 3 frames

@ 2 EV apart.• ISO set as low as possible (I prefer ISO 100 or lower if

camera has ability).• Workflow: Most underexposed to most overexposed

(if possible). Your choice!• Lock Focus (When possible & plausible, use manual

focus.)• For landscape - f-8 or higher is recommended. I like

f/11 or f/16.

Next Steps

Page 29: Hdr magic

Working The Image1. Download the image to your HD/External HD2. For today, the Desktop is the perfect location3. Open up your image browser (Bridge is great)4. Three ways to load files in Photomatix

a. Drag & drop from Bridgeb. Use the Lightroom 2.0 plug-in (sends them as TIFF files)c. Automate (batch processing)

5. Generating the HDR (Radiance [.hdr])file.

Page 30: Hdr magic

The Photomatix Pro Interface

Click on “Generate HDR Image”

Page 31: Hdr magic

Now… Click On Browse

After the files are loaded, click on OK.The next screen shows the dialog box

which appears after clicking OK.

Page 32: Hdr magic

Set your parameters:

• If working from 1 file, Align source images is not necessary.

• Use “matching features” as it also does rotational correction.

• I do not always use the “Attempt to reduce ghosting artifacts.” It depends on what I am after. However, it is good to leave it checked by default and remove the check mark if not needed.

• Make adjustments to white balance if needed.

• My color space is set for Adobe RGB (1998)

• Click on OK

Page 33: Hdr magic

Your Next Window is an HDR Viewer

2) Now click on “Tone Mapping”

1) Before starting the Tone Mapping sequence, click on: File/Save As/.hdr should be in the dialog box/Save.

Detail Enhancer Settings

• Strength: Controls the strength of the contrast enhancements; locally and globally.

• Color Saturation: Controls the saturation from grayscale to pure color in the image.

• Luminosity: Controls the compression of the tonal range, thereby affecting the global luminosity range. The higher the setting, the brighter the mid-tones and shadows – adds contrast as well.

• Light Smoothing: Controls the smoothing of light variations (two methods: slider or light mode).

Page 36: Hdr magic

Detail Enhancer Settings

• Microcontrast: Sets the amount local details are accentuated.

• White & Black Points: Controls the clipping points of the shoulder and toe of the tonal curve.

• Gamma: Adjusts the midtone of the image.

• Temperature: To the left is cooler; to the right, warmer.

• Saturation Highlights & Shadows: Enhances the primary saturation control allowing fine tuning.

Page 37: Hdr magic

Detail Enhancer Settings

• Micro-smoothing: Used to smooth local details enhancements.

• Highlights Smoothing: Use to keep highlights from turning gray or to reduce halos around objects.

• Shadows Smoothing: Reduces contrast enhancements in the darker areas of the image.

• Shadows Clipping: Controls the shadow clipping and is handy for reducing noise in dark areas of an image taken in low light.

After Tone Mapping… Process The Image

Click on “Process” after Tone Mapping your image

Page 39: Hdr magic

Processing the Tone Mapped Image

The Magic is in the Tone Mapping!!

When Photomatix completes the processing phase, it will provide a preview image in the window. You are now able to tone map the image again if you so desire.

If you like what you see… File/Save As/TIFF (16 bit). There is a check box on the Save As window to “Open in Image Viewer” and I keep this checked with PS4 as the default program.

Page 40: Hdr magic

Adobe Photoshop™• Use Photoshop to generate an HDR file• It’s great – wonderful in fact – at combining

files accurately• It STINKS – and I’m being very nice – at tone-

mapping• To generate an HDR image file in PS…– Go to Bridge– Tools/Photoshop/Generate HDR (see next slide)

Save As Radiance (.hdr)

Page 45: Hdr magic

What Now?

Open the Radiance (.hdr) file in Photomatix Pro and, you guessed it… Tone Map the image anyway you like it.
