Diagnose the missing visual evidence
The untouched original plus one close crop of the hardest text.
What the pixels control
Missing character edges limit OCR. Strong filters cannot restore lost evidence.
When to recapture
Retake the photo when two possible characters would change the meaning.
The recovery limit
Recapture first, edit lightly, and preserve uncertainty when the pixels do not support a confident reading.
Decide whether to recapture
Zoom into the smallest important text. If strokes merge or a single character occupies only a few pixels, take another photo. Move closer, steady the phone, tap the text to focus, and use even light without glare.
If recapture is impossible, crop one short region at a time. Smaller crops give the OCR engine fewer competing shapes and make it easier to compare uncertain words with their location in the source.
Use restrained corrections
Rotate the page upright and make mild brightness or contrast changes. A grayscale copy can help colored text on a patterned background. Avoid strong sharpening, denoising, or threshold filters that create strokes not present in the source.
Keep the untouched original beside every edited copy. If two preparations produce different names or numbers, the source is not reliable enough for automatic use.
A quick pass through the OCR image readiness checker can help distinguish measurable image limits from problems that still need visual judgment.
Mark uncertainty honestly
Read the extracted text before translating it. Replace a genuinely unreadable span with a visible marker rather than guessing. Context may narrow possible meanings, but it cannot restore missing pixels.
For addresses, safety warnings, medicine, legal text, serial numbers, or prices, find a clearer source or ask a person who can inspect the original. A fluent translation cannot validate a blurred character.
When reflection rather than focus is hiding letters, use the glare removal workflow for photo translation before applying stronger image filters.
Recover and translate difficult photo text with safer recapture, crop, contrast, and verification choices instead of aggressive filters. Continue with the photo quality and ocr guide collection for adjacent workflows.
