Different lighting fixed	`combine both photos with consistent lighting appearance`	30s
With date labels	`side-by-side with matched lighting, add date labels`	30s

How it works

Upload both progress photos

Drop your before and after weight loss photos into EditThisPic. JPG, PNG, WebP up to 7MB each. Can be mirror selfies, gym photos, progress check-ins—any photos showing your weight loss journey.

Expect: Simple side-by-side creation: 25-30 seconds. Complex lighting matching or background cleanup: may need one additional refinement.
Describe how to combine them

Type 'create side-by-side comparison with matched lighting' or 'combine before on left, after on right, match the lighting so they look consistent.' The AI aligns the photos, matches brightness and color, and creates the professional progress photo format.

Tip: Specify 'before on left, after on right' if that matters to you—the standard convention helps viewers immediately understand the transformation direction.

Check alignment and consistency

Verify both photos are properly aligned—same body position, same height in frame. Check that lighting looks consistent so viewers see body changes, not lighting tricks. Zoom in to make sure faces and body proportions match in scale.
Adjust matching if needed

If lighting still looks different or one photo needs adjustment, describe the specific issue: 'brighten the before photo to match after' or 'both photos should have same warm tone.' For alignment issues, request 'align both photos so faces are at same height.'

Tip: Add a date label to each photo ('Jan 2025' and 'Jan 2026') to show the timeline—makes transformations more impressive and credible.

If something looks off

Side-by-side layout has one photo larger than the other

Why: Original photos have different aspect ratios or resolutions, causing size mismatch in side-by-side layout.

Try: create side-by-side with both photos exactly the same size and height, crop if needed to match dimensions

Try This →

Tip: Specify 'same height' or 'equal size' to ensure balanced side-by-side appearance.

Lighting matched but transformation is now less visible

Why: Over-matching can reduce the contrast that makes body changes obvious—too much consistency hides progress.

Try: match lighting enough for consistency but preserve the visible body shape and muscle definition differences

Try This →

Tip: Goal is consistent conditions, not identical photos—the body changes should still be dramatically visible.

Photos aligned but faces/bodies at different heights in frame

Why: Camera distance or body position changed between photos, creating vertical misalignment in comparison.

Try: align both photos so faces are at the same height and body positions match vertically

Try This →

Tip: Vertical alignment is critical—viewers need to compare equivalent body areas at same eye level.

Background matching made the photos look fake or overly edited

Why: Aggressive background replacement can create artificial-looking results that hurt credibility.

Try: keep original backgrounds but match only the lighting and color tone, don't replace backgrounds completely

Try This →

Tip: Different backgrounds are fine if lighting matches—authenticity is more important than perfection.

Added date labels are too small or hard to read

Why: Default text sizing may be too small for social media or mobile viewing.

Try: add large clear date labels in top corners of each photo, bold text that's readable on mobile

Try This →

Tip: Date labels should be immediately visible—they add crucial context to the transformation timeline.

Color tone matching made skin tone look unnatural

Why: Matching overall color temperature affected skin tones which are sensitive to color shifts.

Try: match lighting and background color but preserve natural realistic skin tones in both photos

Try This →

Tip: Always check skin tone after color matching—unnatural skin destroys transformation credibility.

Quick answers

Do I need to mark anything to create side-by-side progress photos?

No! Just describe what you want: 'create side-by-side comparison with matched lighting' or 'combine before and after with consistent appearance.' The AI understands progress photo requirements and handles alignment, matching, and layout automatically. Markers are only needed if you want to adjust specific areas after seeing the first result.

Why is consistent lighting so important for weight loss photos?

Inconsistent lighting makes people question if the transformation is real body changes or just photo tricks. Bright light makes you look thinner, dim light adds shadows that hide definition. When before and after have different lighting, viewers assume you're manipulating how you look, not showing actual progress. Matched lighting proves the difference is your body, not photography tricks.

Can this work with photos taken months or years apart?

Yes. The AI matches lighting, color, and quality regardless of when photos were taken. Different locations, cameras, and lighting conditions can all be normalized. The only requirement is that both photos show similar angles—front view, side view, etc. You can't match a front photo with a side photo, but any two comparable angles work.

Should I include date labels on my progress photos?

Yes. Date labels show the timeline and make transformations more impressive. '30 pounds in 6 months' is more motivating than undated photos. Add them by including 'add date labels showing start and end dates' in your prompt. Place them in top corners where they're visible but don't cover your body.

How do I make multiple progress check-in photos all match in style?

Use the exact same prompt for all progress photos: 'side-by-side with matched lighting and aligned body position.' This creates a consistent series where all photos have the same layout and appearance. Especially useful for monthly check-ins where you want to track gradual progress over time with visual consistency.
