TEST STRIP
DCTL
SEEING IS DECIDING
COMPARE GRADES
WITH TEST STRIPS
Judging an image in isolation is difficult. Without a direct reference, it’s hard to know whether the image is too dark, too flat, or oversaturated. Side-by-side comparison reveals subtle differences instantly.
Scopes like the waveform or vectorscope provide numerical feedback but lack visual context. The Test Strip DCTL solves this by displaying multiple grading variations simultaneously, allowing precise visual evaluation of exposure, contrast, and saturation.
Inspired by the traditional test strips of photography, this tool applies the same practical approach directly to digital color grading.
EXPOSURE
Visualize incremental exposure adjustments from underexposed shadows to overexposed highlights. Quickly assess how brightness affects overall detail, clarity, and tonality.
CONTRAST
Evaluate how contrast variations shape image depth. Lower contrast results in softer tones and subtle gradations; higher contrast enhances definition, drama, and visual impact.
SATURATION
Observe color saturation changes clearly and precisely. From muted or monochromatic tones to vibrant, richly saturated hues – immediately identify the ideal intensity for your image.
TEST STRIP DCTL
- Split Mode
Enables the split view. - Split Full Frame
Spreads each variation across the full image. - Exposure 0.5 Stop / 1.0 Stop
Increases exposure by 0.5 or 1 stop per split. - Exposure Flip
Reverses direction—each step decreases exposure. - Contrast Shift 0.100 / 0.200
Increases contrast incrementally. - Contrast Flip
Makes contrast go down instead of up. - Saturation 0.100 / 0.200
Boosts saturation per step. - Saturation Flip
Reduces saturation in each split. - Monochrome
Converts the image to black & white. - Show Values
Displays exposure, contrast, and saturation values in each split.
THE FASTEST WAY TO
EVALUATE A GRADE
By displaying these variations side by side, this Test Strip DCTL provides an instant comparison, helping to quickly evaluate the impact of different contrast and saturation settings. Instead of adjusting values one by one and switching between versions, this approach streamlines the decision-making process, making grading more intuitive and efficient.
The left set of three images presents a progression where contrast and saturation are adjusted from left to right. Contrast increases gradually across the frame, starting at +0.900, then +1.000, and reaching +1.100. At the same time, saturation decreases from +0.200 to 0.000, and finally to -0.200, creating a shift from a warmer, more saturated look to a cooler, more subdued one.
The right set also shows a progression in contrast and saturation from left to right. Contrast again increases from +0.900 to +1.000, and then to +1.100. However, unlike the left set, saturation moves upward from -0.100 to 0.000, and finally to +0.100 — resulting in a transition from a slightly desaturated look to a richer, more vibrant one.
With just a couple of clicks, you can combine and flip contrast, saturation, and exposure values to generate quick, structured look comparisons — perfect for look development and presenting options to clients.
