Editing

The photo is just the beginning. With the right workflow, you transform good shots into great images — no magic, just control.

Play with Brightness, Contrast & Color

Editing isn't magic — it's targeted adjustments. Drag the sliders and see live how the image changes.

Controls
Brightness 100%
Contrast 100%
Saturation 100%
Blur 0px
Tip: Always start with exposure and contrast before touching colors. Blur simulates softness — in real editing you would use sharpening masks instead for selective sharpening.

The RAW Workflow in 4 Steps

From memory card to finished image — every pro follows this process. Click the steps to see details.

Click a step for details

Step 1: Import & Selection
  • Copy RAW files to your hard drive — never edit directly from the card
  • Rate with stars: Mark the best images (e.g. 1–5 stars) to stay focused
  • Tags & collections: Organize by subject, date, or project
  • Never delete files from the filesystem — only hide in the catalog

The 4 Pillars of Editing

No matter which tool you use — these four principles apply everywhere. Master them, and you master every editor.

Correct Exposure

RAW files contain more information than you see. Under- and overexposed areas can often be rescued. Work in this order: Exposure → Contrast → Highlights → Shadows.

Control Color

White balance is the most important color control. A wrong Kelvin value makes warm sunsets cold. Use HSL for selective corrections — e.g. only darken the green of trees.

Crop & Straighten

A good crop can rescue a mediocre image. Remove distracting edge elements, place the subject on rule-of-thirds points, and keep horizons straight. Crop before sharpening.

Selective Adjustments

Not every image needs global changes. Masks, gradient filters, and brushes allow targeted edits: darken only the sky, brighten only the face, sharpen only the eyes.

Editing on Smartphone

You don't need to sit at a computer for great results. Modern apps bring desktop power to your pocket.

RAW Instead of JPEG

Shoot in RAW mode (DNG) if your smartphone supports it. Lightroom Mobile and Snapseed edit RAW files with full dynamic range — that makes the difference.

Presets as Starting Point

Presets (Looks, Filters) are not cheating — they are a starting point. Choose a look close to your image, then adjust the sliders individually.

Selective Adjustments

Snapseed and Lightroom Mobile allow point adjustments. Tap an area and adjust brightness, contrast, or saturation only there — without affecting the rest.

Cloud Sync Workflow

With Lightroom Mobile, edit on the go and find your edits later on desktop. The workflow is seamless — ideal for on-the-road and at home.

The 80/20 Rule of Editing

80% of the result comes from 20% of the sliders. Focus on: Exposure, Contrast, White Balance, and Cropping. Everything else is fine-tuning. A well-captured image needs barely any editing.

Smartphone tip: Use the "Auto" feature as a starting point, but always check white balance and exposure manually. AI often gets it wrong.

Practice: Editing Training

Three exercises that sharpen your workflow:

Exercise 1: The Same Look

Edit 5 images (different subjects) with the same style:

  1. 1
    Create a preset
    Edit the first image until satisfied. Save the settings as a preset/Look.
  2. 2
    Apply to 4 more images
    Import 4 more images and apply the same preset.
  3. 3
    Adjust individually
    Each image needs fine-tuning. Exposure and white balance will differ for every image.

Learn how differently the same preset affects various subjects.

Exercise 2: Rescue Mission

Choose a technically bad image (underexposed, wrong color, blurry):

  1. 1
    Rescue exposure
    Lift shadows and pull back highlights. Where are the limits of the RAW file?
  2. 2
    Correct white balance
    Use the eyedropper white balance on a neutral area. Compare with manual Kelvin.
  3. 3
    Best possible result
    Edit the image as well as possible. When does it become too much? When does it look over-edited?

This exercise shows you the limits of post-processing — and why good captures matter.

Exercise 3: Mobile Editing Challenge

Edit an image completely on your smartphone:

  1. 1
    Shoot RAW
    Use Pro mode or RAW mode on your smartphone. Photograph a subject with high contrast.
  2. 2
    Edit in Lightroom Mobile
    Exposure, contrast, color, sharpness, cropping — everything on the phone.
  3. 3
    Compare in Snapseed
    Export the image and open it in Snapseed. Which app feels better? Where are the strengths?

Compare the result with a desktop edit of the same image.

Quiz: Editing

Why should you always shoot in RAW format if you plan to edit?

Because RAW files are smaller than JPEG
Because RAW contains more image information and dynamic range
Because RAW can be viewed directly in the browser

What is the first step in the RAW workflow?

Import and select the best images
Start color correction immediately
Export the image as JPEG

What is the difference between saturation and vibrance?

There is no difference
Vibrance makes everything more colorful
Vibrance protects skin tones, saturation affects all colors equally

Which tool is best for free desktop RAW editing?

Lightroom Mobile
darktable
Snapseed

Which format is best for web export?

JPEG with sRGB color space
TIFF without compression
RAW file directly
