Before You Generate
- Write the goal in one sentence before you open the tool.
- Gather your real material first: facts, numbers, names and constraints.
- Decide what done looks like - length, format, tone and audience.
- Set aside five uninterrupted minutes; context switching costs more than the task.

Mistakes to Avoid
- Sharpening a badly out-of-focus photo and amplifying the blur
- Pushing strength until white halos outline every edge
- Sharpening noisy photos and making noise look like detail
- Sharpening more than once on the same file
A 10-Minute Practice Routine
- Two minutes: write the brief for a real task on your list.
- Three minutes: generate and read the result end to end.
- Four minutes: edit - real details in, generic lines out, opening rewritten.
- One minute: save the prompt and note one thing to change next time.
How to Know You Are Improving
Track edit time per result for two weeks. When it drops, your briefs are getting better. When it spikes, the cause is almost always a vague input - go back to the tip about writing the goal in one sentence.
Frequently Asked Questions
Can sharpening fix a completely blurry photo?
No - it enhances existing edges. Photos far out of focus need cropping or AI reconstruction instead.
How much sharpening is right?
Enough that details read clearly at normal viewing size, with no visible halos. When in doubt, less is more.
Should I sharpen before or after resizing?
After - sharpening is tuned to the final pixel size, so resize first, sharpen last.
Is my photo uploaded?
No - the effect runs in your browser and the file stays local.
