Different edits change different information
A color preset and a face reshaping effect are different transformations. Before comparing their estimates, identify what the editing tool changes. Some presets combine several effects under one name.
| Edit | What changes |
|---|---|
| Brightness or contrast | The light and dark values and visibility of detail. |
| Skin smoothing | Local texture and fine detail. |
| Face reshaping | The position or proportions of facial features. |
| Stickers or overlays | Parts of the face may be covered. |
| Export compression | Fine detail may be lost even without a visible filter. |
There is no fixed number of years a filter removes
A model does not receive the name of the filter or its intended effect. It receives the edited photograph. Even an effect labelled as rejuvenating does not guarantee a lower age prediction.
Lucentage has not published a benchmark isolating the effect of individual filters. This guide gives you a comparison method, not measured claims about particular apps or a promised change in years.
Compare edits of one original photo
Start with a clear photo of yourself or another consenting adult. Keeping the original capture fixed makes this a different experiment from taking several new selfies.
- Keep the original untouched and make separate editing copies.
- Export an unedited control copy through the same editor to help identify changes caused by exporting alone.
- Apply one effect to one copy. Record the tool, effect name and intensity.
- Use the same crop, dimensions and export settings for the control and edited copies.
- Upload the original, control and edited copy. Write down all three estimates.
- If trying another effect, start again from the original instead of layering it over the previous edit.
Read the difference carefully
Compare the edited copy with the exported control first. If the original and control already differ, the export process changed the input enough to matter in that comparison. You cannot attribute the entire original-to-edit difference to the filter alone.
A result from one portrait applies to that portrait and those settings. To describe a general effect, you would need a documented evaluation with more people and a consistent procedure. Keep a small personal experiment labelled as such.
No change in the displayed age does not prove that the edit had no effect internally. The interface shows a whole-year estimate, which can hide small differences.
Which version should you use for a normal estimate?
Use a clear original with optional beauty effects disabled. That gives you a straightforward reference for future comparisons. Choose filters for the look you want in a shared photo, while treating any resulting age change as the model responding to an edit.
