Post-processing is where good photos become great, but it can also be where many photographers get stuck. Between all the sliders, tools, and techniques, it’s easy to lose track of what really makes a difference.
One of the most important concepts to master is the difference between global and local adjustments. It might sound technical, but understanding how and when to use each is what separates an average edit from a professional one.
Global adjustments set the overall mood of your image: the light, color, and contrast. Local adjustments, on the other hand, let you shape the finer details: brightening a foreground, enhancing a subject, or adding depth exactly where it’s needed.
In this article, you’ll learn how both work, when to use them, and why combining them is essential for creating images that truly reflect your vision.
What are Global Adjustments?
Global adjustments are the first step in almost every photo edit. They’re the tools that affect the entire image at once, setting the overall mood, brightness, and color balance before any fine-tuning begins.
If you open Lightroom, DxO PhotoLab, or any RAW editor, you’ll find most of these adjustments in the main development panel. Sliders such as Exposure, Contrast, Clarity, and Saturation are all examples of global adjustments.
When you move one of these sliders, the change applies to the entire photo, not just specific areas.
For example:
- Exposure: Increasing exposure brightens the entire image; decreasing it darkens everything.
- Contrast: Adjusting contrast affects the tonal range throughout the image, making shadows darker and highlights brighter (or vice versa).
- Saturation: Increasing saturation intensifies every color in the frame, not just selected ones.
Even sliders that seem targeted, like Highlights, Shadows, Whites, and Blacks, are still considered global adjustments. That’s because they apply the same correction to all areas of similar brightness or tone, rather than isolating a single subject or region.
Global adjustments are essential for building your foundation. They help you define the overall light, color, and atmosphere of a photo.
However, they come with a limitation: you can’t choose where the adjustment applies. Every change you make impacts the entire image equally, which is why local adjustments become so powerful later on.
Most Common Global Adjustments in Post-Processing
While almost every slider in a RAW editor affects the entire image, a few are especially important when setting the visual tone of your photo:
- White Balance: Adjusts color temperature and tint, helping neutralize color casts or enhance warmth and coolness. It’s the foundation of your image’s overall color mood.
- Exposure and Contrast: Control the overall brightness and tonal range. This is where you decide whether your photo feels bright and airy or dark and moody.
- Saturation and Vibrance: Influence how colorful the image appears. Vibrance targets less-saturated tones for a balanced result, while Saturation boosts all colors equally.
These are just a few of the global adjustments you’ll find in your photo editor, but they go a long way in creating the desired atmosphere of your photo before you begin refining specific areas.

Examples of Before and After Global Adjustments
Even though global adjustments affect the entire photo, they can have a dramatic impact. Subtle exposure, contrast, and color corrections can completely transform an image’s atmosphere.
That said, it’s easy to go too far. Strong global adjustments often lead to unnatural results, crushed shadows, clipped highlights, or oversaturated colors. The key is moderation: make small, deliberate moves and let them work together to build the look you want.
What are Local Adjustments?
While global adjustments affect the entire image, local adjustments let you target specific areas of a photo.
They’re how you brighten a foreground without touching the sky, enhance the glow around a sunset, or bring back texture in just the mountains, not everywhere at once.
In practice, local adjustments often use the same sliders as global ones (Exposure, Contrast, Saturation, and so on), but with one key difference: they’re applied through a mask.

Masks tell your editing software where to apply the adjustment. In Lightroom, DxO PhotoLab, Luminar Neo, and similar RAW editors, this process is straightforward and visual. In Photoshop, you get even more precision by combining masks with layers.
Let’s revisit one example:
When you move the Exposure slider normally, the whole image gets brighter or darker, that’s a global adjustment. But if you use a Linear Gradient Mask to target only the lower part of the image (like the foreground), the change applies only there. You’ve now turned a global adjustment into a local one.
This selective control gives you far more flexibility. You can shape light, color, and detail exactly where you want them, guiding the viewer’s attention and balancing the composition. It’s one of the most important skills to develop in post-processing.
Most Common Local Adjustments
Local adjustments use the same familiar sliders, but instead of affecting the whole image, they’re applied only inside your selected mask.
In Lightroom, you can create masks using several powerful tools:
- Subject: Automatically detects and selects the main subject.
- Sky: Targets the sky, ideal for darkening bright clouds or adding contrast.
- Background: Separates the background from your subject for easier control.
- Objects: Lets you click and mask specific objects automatically.
- Brush: Manually paint over areas you want to adjust.
- Linear Gradient: Gradually applies adjustments in a line (perfect for horizons or foregrounds).
- Radial Gradient: Applies adjustments in a circular area, great for creating subtle vignettes or enhancing light around a subject.
- Range: Targets specific luminance, color, or depth ranges for advanced control.
If you’re working in Photoshop, masks can be even more precise; you can attach one to any layer or adjustment, giving you near-limitless flexibility.
In combination with these masking tools, here are some of the most useful local adjustments for photographers:
- Local Contrast: Instead of applying contrast globally, use a luminosity mask to adjust only midtones or key regions, preserving delicate highlights.
- Local Sharpening: Sharpen the landscape while leaving skies or smooth areas untouched to avoid unwanted noise. [Read More: The Best Web Sharpeners for Photoshop. Goodbye Soft Images!]
- Dodging and Burning: A timeless technique for brightening or darkening selected areas to add depth, shape, and emphasis. [Learn more about dodging and burning here]
- Local Color Adjustments: Adjust the hue or luminance of specific colors, such as warming the oranges in a sunset or cooling the blues in distant shadows.
The exact tools vary between editors, but the concept remains the same: local adjustments let you control exactly where and how your changes appear, adding subtlety, dimension, and polish to your work.
Examples of Before and After Local Adjustments
Local adjustments are where a photo often comes to life. After setting the base look with global edits, selective adjustments allow you to fine-tune light, enhance color harmony, or guide attention to your subject.
A few well-placed local edits can transform a flat image into one that feels balanced, intentional, and atmospheric, all without losing the natural look of the scene.
Global vs. Local Adjustments
Now that you understand both global and local adjustments individually, it’s time to look at how they compare and how to know when each approach is best.
Global adjustments work across the entire image, while local adjustments target specific areas. Both are essential parts of a complete post-processing workflow, but each has its strengths and limitations.
Advantages and Disadvantages of Global Adjustments
Global adjustments are your first step in building a photo’s foundation. They’re fast, efficient, and help you define the overall brightness, contrast, and color balance before you move into more detailed work.
Advantages of Global Adjustments:
- Quick and easy to apply, ideal for the early stages of editing.
- Great for establishing the overall look and mood of a photo.
- Works well for batch editing or applying consistent corrections across multiple images.
Disadvantages of Global Adjustments:
- Lack of precision, changes affect every part of the image equally.
- Can unintentionally alter areas that were already well-balanced (for example, oversaturating bright colors).
- Less effective for targeted refinements like selective exposure or color work.
Global adjustments are efficient and necessary, but on their own, they can only take your edit so far.
Advantages and Disadvantages of Local Adjustments
Local adjustments give you control where global tools stop. They allow you to refine your photo with precision, adjusting light, color, or texture in just the areas that need attention.
Advantages of Local Adjustments:
- Full control over where changes are applied.
- Let you emphasize subjects, balance exposure, or guide the viewer’s eye.
- Ideal for creative shaping, adding depth, contrast, and atmosphere.
Disadvantages of Local Adjustments:
- More time-consuming than global edits.
- Require a deeper understanding of masks, layers, and selection tools.
- Overuse can lead to an unnatural or inconsistent look if not handled carefully.
Local adjustments take more effort, but they’re what turn a technically correct image into a visually compelling one.
When to Use Global or Local Adjustments
There’s no one-size-fits-all rule in post-processing; every image is different. Some photos only need a few global tweaks to look complete, while others demand more targeted attention.
A good general workflow is:
- Start with global adjustments to set the foundation: correct exposure, color, and tone.
- Move to local adjustments to refine specific areas: balance highlights and shadows, enhance details, or add creative emphasis.
- Review and balance; toggle between the two approaches to ensure your edits feel natural and cohesive.
Think of global adjustments as setting the stage and local adjustments as directing the spotlight. When used together, they give you both speed and control, the two pillars of effective post-processing.

Combining Different Adjustments
The real magic in post-processing happens when you combine both global and local adjustments. It’s not about choosing one over the other, it’s about knowing when and how to use each.
Here’s a simplified version of how I often combine both in my own workflow:
- Start with global adjustments in Lightroom.
Begin by setting the foundation; adjust White Balance and the basic Tone sliders (Exposure, Highlights, Shadows, Whites, and Blacks) to balance the overall image.
Then move into the Color Mixer to fine-tune hues and saturation for each color range.
I’ll also apply a bit of input sharpening in the Details panel to bring out clarity and texture.
These steps establish the mood of the photo and form the base of my global edits. - Add simple local refinements in Lightroom.
Once the global look is in place, I create Linear or Radial Gradient Masks to adjust exposure and saturation selectively.
This might mean darkening the foreground and sky, or increasing light where I want the eye to go. - Finish with precise local adjustments in Photoshop.
After Lightroom, I move into Photoshop for more advanced work.
Here, I’ll apply midtone contrast, dodging and burning, and local exposure and color corrections.
I often use one or two filters in Nik Color Efex to subtly enhance contrast and atmosphere.
This process may sound complicated, but it becomes pretty intuitive once you get used to it. Global adjustments shape the foundation; local adjustments bring it to life. Together, they help you create balanced, dynamic images that still feel natural and true to the scene.
Recommended Software for Global and Local Adjustments
Choosing the right software can make a huge difference in how efficiently and creatively you work. Most modern photo editors include tools for both global and local adjustments, but each handles them a little differently.
Here are a few of the best options, all of which I’ve personally worked with over the years:
Adobe Lightroom Classic
Lightroom remains the go-to choice for many photographers, and for good reason. It combines powerful global tools with intuitive local adjustments, all within a single, streamlined workflow.
The Masking panel makes it easy to apply precise local edits like darkening skies, enhancing light, or balancing exposure, while still keeping all your global sliders at hand.
If you want an efficient all-in-one editing environment, Lightroom is an excellent place to start.
Note: If you find Lightroom overwhelming but want to easily apply advanced techniques, the Lightroom Toolbox might be a good match for you.
Adobe Photoshop
Photoshop is where you get absolute control. It’s more advanced and less streamlined than Lightroom, but its layer-based workflow means every adjustment can be applied locally, globally, or anywhere in between.
You can combine multiple masks, use luminosity masks, or fine-tune specific areas with precision that’s unmatched.
I often finish my edits here after starting in Lightroom, especially when applying dodging and burning, color refinement, or midtone contrast.
DxO PhotoLab
PhotoLab is one of the most underrated tools on the market. It’s intuitive, fast, and its U Point technology for local adjustments is remarkably accurate.
Combined with DeepPRIME noise reduction and powerful lens corrections, it’s an ideal alternative for those who want professional-level quality without the complexity of Photoshop.
PhotoLab handles both global and local adjustments beautifully, and it integrates seamlessly with DxO’s Nik Collection.
Luminar Neo
Luminar Neo is perfect if you want an approachable, AI-assisted workflow without losing creative control.
Its Relight, Enhance, and Structure tools act as smart global adjustments, while local masking tools let you refine areas with just a few clicks.
It’s especially appealing to those who prefer quick results, making it a great entry point for photographers new to post-processing.
Conclusion
Mastering both global and local adjustments is one of the biggest steps toward creating images that truly reflect your vision. At first, the tools might feel overwhelming, but as you practice, you’ll start to see how each one plays a role in shaping light, color, and mood.
Global adjustments are your foundation. They set the overall tone of the image, the brightness, contrast, and color balance that define its first impression.
Local adjustments come next, allowing you to refine and direct attention exactly where you want it. They give you the freedom to highlight a subject, recover detail, or subtly guide the viewer’s eye through the frame.
The real power comes from knowing how to blend the two. Global edits give structure and cohesion; local edits add depth and emotion. When used together, they transform your post-processing from basic corrections into expressive image-making, helping your photos look not only polished, but personal.
