Histogram

What is Histogram?

A histogram is a valuable tool for photographers, depicting how pixels in an image are distributed across various brightness levels. It charts the number of pixels at each intensity, revealing insights into shadows, midtones, and highlights:

Shadows: Located on the left side of the histogram.
Mid-tones: Positioned in the center.
Highlights: Appearing on the right side.

By analyzing a histogram, you can easily determine if an image has sufficient detail for effective adjustments.

Histograms also offer a quick overview of an image’s tonal range, helping to identify its “key” type:

Low-Key Image: Concentrates details in the shadows.
High-Key Image: Focuses on highlights.
Average-Key Image: Dominates with mid-tones.
Full Tonal Range: Spreads pixels across all parts of the histogram.

Recognizing the tonal range allows you to make informed color adjustments to improve your photo.

The Histogram is floating at the top of the preview page.

Note: You will be able to adjust the Histogram location and move to anywhere you want in the preview section.

Basic

The basic feature group including the basic color adjustment of the image such as White Balance or Color Tone

White Balance

The purpose of adjusting the white balance is to eliminate color shifts in a picture so that white becomes neutral under different light sources, and the color of the picture can become more accurate and more realistic.

As Shot — Keep the white balance of the image as the way while taking the shot.

Auto — The auto white balance function adjusts the color deviations created by the source light. It corrects colors so that white objects appear as white, thus bringing the overall color closer to what the human eye can see. Only RAW files are supported for selecting different white balance types.

Daylight: Adjusts for sunny outdoor conditions.
Cloudy: Adjusts based on cloudy day’s light condition.
Shade: Adjusts for shadow locations.
Tungsten: Adjusts for incandescent lighting or bright light used in the studio.
Fluorescent: Adjusts for fluorescent lighting.
Flash: Adjusts for the flashlight.

Temp — Allows you to adjust shifts in the color balance between warm (yellow) and cool (blue) tones.

Tint — Tint adjusts the color balance between green and magenta tones.

Tone

Tone is crucial in photography as it defines the balance of light and dark, color, and contrast in an image. Skillful tone management can enhance a photo’s visual appeal.

Dark tones are captured in shadows, while bright tones appear in highlights. Natural photographs typically feature a blend of tones, which adds depth and dimension.

The significance of tone goes beyond aesthetics; it conveys the emotion of a photograph and affects how viewers perceive it. Proper use of tone enables photographers to express creativity and emotion more effectively, helping viewers grasp the photo’s theme and sentiment.

Exposure — Adjusts the overall lightness or darkness of the image, enhancing its visual impact and quality from various aspects.

Contrast — Enhancing contrast boosts brightness and saturation, making the image more vivid. Reducing contrast softens the image, adding texture and detail.

Brightness — This slider improves image brightness while maintaining contrast, offering a balanced enhancement across tones.

Highlight — Alters the lightest parts of the image, adjusting their brightness and tint to refine these areas.

Shadow — Modifies the darkest parts of the image, changing their darkness and tint to better define shadowed regions.

White — Controls the brightness of the brightest elements in the image, affecting overall luminance.

Black — Adjusts the darkest elements, influencing overall darkness and contrast within the image.

Clarity — Increases sharpness and detail, reducing blur. Lowering clarity results in a softer, less detailed image.

Vibrance — Enhances muted colors while preserving already saturated ones, creating a natural and balanced look.

Saturation — Adjusts color intensity; lower values mute colors, while higher values make them more vivid.

Curve

Curve is a feature that adjusts the brightness, contrast, and color balance of a picture, adjusting it to result in a better color performance and visual effect.

Evoto iPad app provides a comprehensive set of curve adjustment tools which can be divided into four types: parametric curve, RGB curve, Luma Curve and single-channel curve for three primary colors.

Parametric Curve

The Parametric curve is divided into four sections using shadow, midtone, and highlight segmentation points. From left to right, the sections represent shadows, dark tones, light tones, and highlights.
Four sliders below the curve correspond to these sections, each with a range of -100 to +100.
Adjusting the curve graph automatically updates the slider values, and vice versa.

RGB Curve, Luma Curve and R/G/B Channel Curves

Allow control point adjustments on the curve.
Support up to 16 control points for precise tonal and color modifications.

On-image Adjustment Tool

Clicking the On-image adjustment tool in the image adds control points to the curve. Moving the control points adjusts the tonality of the image.

Dashed lines represent the range for adding points on the curve.
Solid lines indicate points already added to the curve.
How to Add control Points:
1. Click the blue checkmark next to the circle. Once the control point is confirmed, the blue checkmark disappears and the dashed circle becomes solid.
2. Adjust the slider below the circle. After confirming the control point, the slider remains available for further adjustments.

Note:

Clicking on other color modules or tools will exit the On-image Adjustment Tool.

The On-image Adjustment Tool

remains active when switching between different curves.

Long press the channel icon to reset either the specific channel or the entire feature.

When using the Apple Pencil, the following hover effects are available:

For Parameter Curve: Hovering over the curve displays a temporary anchor point and highlights the adjustable range for that specific area (similar to the mouse hover effect on a PC).
For Anchor Point: Hovering over an anchor point reveals the coordinates of the point.

HSL

The HSL color adjustment refers to three key components that allow photographers and image editors to fine-tune the colors in an image:

Hue — represents the actual color itself on the color wheel, such as red, green, blue, etc. Adjusting the hue slider changes the specific shade of each color, allowing you to shift it towards a different hue.

Saturation — controls the intensity or purity of a color. Increasing saturation makes colors more vivid and vibrant, while decreasing it results in more muted or washed-out colors. This adjustment is useful for emphasizing certain colors or achieving a particular mood in your images.

Luminance — affects the brightness of a color. Adjusting the luminance slider can make the color appear lighter or darker without affecting its hue or saturation. This is particularly useful for highlighting or toning down specific colors in a photo to create contrast and focus.

By making adjustments to these HSL values, you have the power to fine-tune the look and feel of your colors, allowing for precise image adjustments.

Evoto iPad provides 8 different colors to adjust, including Red, Orange, Yellow, Green, Aqua, Blue, Purple, and Magenta.

Detail

Please note only when you have adjusted the main Feature (Sharpen, Noise Reduction, and Color Noise Reduction), its sub-features are available to be adjusted.

Sharpen

Sharpen: This slider will enhance the detail and clarity of the image, making it look sharper.

Sharpen – Radius: It will help to determine the range of the Sharpen.

Sharpen – Detail: This controls how the Sharpen should enhance the detail in the image. A higher Detail value will retain more of the smaller details, while a lower value may reduce the effect of the Sharpen.

Noise Reduction

Noise Reduction: It will remove noise from the picture, and the sub-feature to achieve better noise reduction and make the image clearer and more realistic.

Noise Reduction – Detail: Achieve superior noise removal in images with prominent noise by selecting a higher detail value. For images with less noise or when preserving details is crucial, opt for a lower detail value.

Noise Reduction – Contrast: Adjust the noise contrast to make the noise more integrated with the surroundings, thus reducing the prominence of the noise.

Color Noise Reduction

Color Noise Reduction: To remove color clutter in the image, and to make the image clearer and cleaner.

Color Noise Reduction – Detail: Controls the color noise’s threshold. Higher values will maintain more color detail at the edge, but may cause staining. Lower values are more effective at eliminating stains but may cause color bleeding.

Color Noise Reduction – Smoothness: Controls color transition, good for pictures with more color noise. The higher the value, the smoother the color noise transition will be. The higher the smoothness for color noise the easier it will be eliminated, but the details will also lose as it becomes smoother.

Grain

Enhance your photos with a grain texture, adding artistic flair and unique styles. Use the sliders to adjust the intensity of the grain across different tonal ranges, including size, roughness, and color variation.

Overall Grain Strength: Adjusts the general intensity of the grain effect throughout the entire image.

Shadows: Controls the grain intensity specifically within the shadow areas.

Midtones: Adjusts the grain effect in the mid-tone regions.

Highlights: Modulates the grain intensity within the highlight areas.

Size: Alters the size of the grain particles for desired granularity.

Roughness: Changes the texture by controlling the particle fineness.

Color Variation: Modifies the degree of color noise within the grain, affecting its visual diversity.

Lens Correction

Lens Corrections are used to correct or amend the lens distortion, chromatic aberration, and other problems.

Auto Corrections

For RAW files Evoto supports automatic lens correction. The user just needs to select the corresponding camera profile. When the auto-correction toggle is off, all related settings will still be visible but grayed out and unavailable for adjustments. These settings become adjustable only when the toggle is turned on.
Manual adjustment for RAW files is also available.

Manual Adjustment

Distortion Correction: Adjust the barrel or pincushion distortion, keep straight lines straight, reducing or eliminating the effects of lens distortion.
Constrain Crop: Correcting images while maintaining specific content or composition. You can enable or disable it.
Lens Vignetting: Used to correct the vignetting problem in the picture and improve the brightness balance. It will improve the visual effect of the picture by making the overall brightness distribution more balanced and natural.
Midpoint: It deals with perspective distortion or geometric distortion in the picture.

Color Grading

The color grading tool includes four color wheels: Shadows, Midtones, Highlights, and Global.

When adjusting the hue or saturation using the sliders or the wheel, a hue tag indicator appears for better precision.

For each of the Color Wheels, 3 sliders are adjustable:

Hue slider: Range 0–360, default value 0.
Saturation slider: Range 0–100, default value 0.
Luminance slider: Range -100 to +100, default value 0.

For Shadows, Mid-tones, and Highlights Color Wheels, additional adjustments are also available:

Blending slider: Adjusts the overlap between different tonal ranges (0–100, default value 50).
Balance slider: Shifts the balance between shadows and highlights (-100 to +100, default value 0).

Keyboard Integration

When using the keyboard, holding down the Shift key will display an auxiliary line for saturation adjustment.

Long press the Color Wheel icon to reset either the specific color wheel or the entire feature.

Color Calibration

Color Calibration helps adjust the Hue and Saturation of the three primary colors—Red, Green, and Blue—to fix color issues and make your images look more realistic. Here’s how it works for each color:

Red Primary:

Hue: Changes red tones to lean more towards orange or magenta.
Saturation: Adjusts how intense or vibrant the reds appear.

Green Primary:

Hue: Shifts green tones closer to yellow or cyan.
Saturation: Controls how strong or vivid the greens look.

Blue Primary:

Hue: Adjusts blue tones towards cyan or purple.
Saturation: Alters the brightness and intensity of blues.

These adjustments help ensure colors in your photos are accurate and pleasing to the eye.
