Lightroom Preset Amount Slider — How to Use It (2026)
The preset amount slider in Lightroom is one of the most useful features most photographers never use. It controls the strength of a preset — from 0% (no effect) to 100% (full preset) — letting you blend presets at any intensity between the original photo and the full look.
This guide covers exactly how to use the amount slider in both Lightroom Mobile and Lightroom Classic.
Where to find the amount slider
In Lightroom Mobile: Apply a preset to any photo. A slider appears at the bottom of the screen immediately after application. Drag left to reduce the preset strength, right to increase it. The slider disappears when you tap elsewhere — tap the preset name again to bring it back.
In Lightroom Classic: Go to Develop > Presets panel. Hover over any preset and a small slider appears at the bottom of the preview tooltip. Or apply the preset and find the "Amount" slider that appears in the Presets section of the panel.
What the amount slider actually does
The amount slider blends between your original photo settings and the full preset settings.
At 100%: the preset is fully applied — all adjustments at their saved values. At 50%: every adjustment is at half strength — halfway between the original and the preset. At 0%: no effect — the photo is at its original unedited state.
This is not the same as reducing individual sliders manually. The amount slider proportionally reduces every adjustment in the preset simultaneously — tone curve, HSL, color grading, grain, everything scales together.
When to use the amount slider
When a preset is too strong. Some film presets have heavy grain, strong color grading, or significant tonal shifts that work perfectly on some photos but are too intense on others. Rather than manually adjusting each slider, reduce the amount to 60-80% and the preset scales back proportionally.
When you want a subtle film look. For photographers who want just a hint of analog character without a full film look — 30-50% is a useful starting point. The film characteristics are visible but subtle.
When blending two looks. Apply Preset A at 100%, then apply Preset B at 50%. The result blends elements of both. This works particularly well for combining a film base preset with a specific color grade.
For gradual testing. When trying a new preset, start at 50% and move up or down from there. It gives you a better sense of the preset's characteristics before committing to full strength.
Amount slider tips
The 70% sweet spot for film presets. Many film presets are calibrated for maximum authentic film quality at 100%. But on digital photos — particularly iPhone photos — 70-80% often looks more natural while retaining the core film character.
Different amounts for different photos. In a single session, bright outdoor photos may need the preset at 80-90% while darker indoor photos need it at 60-70%. The amount slider lets you adapt the same preset to different photos without creating separate preset variations.
Amount does not save with the photo. The amount slider position is not remembered if you tap away and reapply. It always resets to 100% on fresh application. Apply at the amount you want and then fine-tune manually if needed.
Combine with manual adjustments. Apply the preset at a reduced amount, then add specific manual adjustments on top. For example: A6 at 70% plus manual Orange Luminance +5 plus Temperature +100. This gives you the preset's core character with your specific customization.
Free preset to test the amount slider
Download the free A6 preset and test it at different amounts on the same photo — 30%, 60%, 90%, and 100%. This gives you a clear sense of how the amount slider works and what range suits your style.
FAQ
Does the amount slider work on all presets?
Yes — it works on any preset applied in Lightroom Mobile or Classic, including presets you have downloaded and presets you have created yourself.
Can I save a preset at a specific amount?
In Lightroom Classic, you can create a new preset from the current state of a photo — apply the preset, reduce the amount, then create a new preset from that state. This saves the reduced-strength version as a new preset.
Why does reducing the amount not simply reduce all sliders by the same percentage?
It does. The amount slider proportionally scales every adjustment in the preset. A Exposure adjustment of +0.5 at 100% becomes +0.25 at 50%. A Color Grading shadow saturation of 20 becomes 10 at 50%.
Is the amount slider available in the free version of Lightroom Mobile?
Yes — the preset amount slider is a free feature in Lightroom Mobile.
