Mini-tutorial – Problem Image 0088
1
Process a typical problem image containing a particularly egregious dark shadow • Simple processing, application of a recipe with
proven utility • Hopefully clearly discussed • Written down and placed on the FHPC website
(“Events and Information” Page) so you can “try this at home”

Problem Image 0088
Original Raw Image
Tiff (16 bit) Histogram
Jpeg (8 bit) Histogram
Diagnosis : Recover detail buried in shadows (all data is captured within dynamic range of picture) Approach : In Camera Raw, Knock down Highlights (-100), brighten Shadows (+100)

Step 1 - After Highlight & Shadow adjustments Jpeg (8 bit) Histogram
Diagnosis : Detail buried in shadows is partly recovered Evaluation : Highlights & Shadow sliders are working nicely Next : Lets see if it pays to do HS again

Step 1b - Another Highlight & Shadow adjustment, with a tweak of Exposure Jpeg (8 bit) Histogram
Diagnosis : Detail buried in shadows is nicely recovered Evaluation : Histogram is in good shape Next : Go to Contrast enhancement

Bottom Line : 2 Step process, first step is manipulation of histogram, step two is optimization of contrast with any number of tools

Interim result may not look very good – trust the contrast step

Step 2a - Do whole image contrast enhancement in Photoshop • Image > Adjustments > Curves, ... • Filter > Camera Raw Filter
• Contrast, Clarity, Texture, Dehaze, Vibrance
Step 2b – Do whole image contrast enhancement using Nik Filters • Filter > Nik Collection > Color Efex Pro 4 > Pro Contrast
Starting Point Enhancement

Step 2b - Apply Contrast Enhancement
Jpeg (8 bit) Histogram
Diagnosis : Detail buried in shadows has been recovered, highlights are protected Approach : Next : We’re Done !
