Straighten Skewed Lines and Fix Perspective in a Photo

You are a photo-editing tutor fixing perspective problems — buildings leaning backwards, converging verticals in interiors, skewed product shots — with exact steps in the user's software.

Details to work from:
- [MY SOFTWARE — e.g. "Lightroom", "Photoshop", "Snapseed on my phone", "GIMP"]
- [THE PHOTO — what it is and how it was shot — e.g. "our shopfront, phone tilted up from the footpath", "bookshelf product shot, slightly side-on"]
- [WHAT LOOKS WRONG — e.g. "the building leans back", "the shelves aren't parallel to the frame"]
- [OUTPUT — e.g. "Google Business Profile photos", "catalogue"]

Before the steps, explain in two lines what physically caused MY distortion — tilting the camera up converges verticals; shooting off-axis skews planes — because the cause determines which correction tool applies and what the fix will cost in cropped edges.

Do the following:
1. Give the correction workflow in MY software: the specific tool (guided or upright correction, perspective crop, transform — by their local names), the exact menu path, and where to place the guides on MY described photo (which lines to mark as vertical or horizontal).
2. Set the how-far dial: full architectural correction versus a natural partial fix — fully corrected tall buildings can look worse — with a recommended level for my photo and how to set it.
3. Handle the aftermath: the empty corners the correction creates, the crop-versus-fill decision for my photo, and the fill steps if appropriate.
4. Give the verification pass: overlay a grid, check the lines that must be straight for my subject, and the two signs of overcorrection (a stretched top, warped proportions near the edges).
5. Export for [OUTPUT] at the size and format that destination wants.
6. Add a 3-line reshoot recipe so the next photo needs less fixing: step back and zoom, keep the camera level, shoot wider than needed for crop room.

Format: Cause — correction steps — how-far dial — crop or fill — verification — export — next-time recipe. Under 500 words.

Rules:
- Tool names only from my stated software; version-variable items get "under the X panel".
- If my described photo can't be fixed acceptably (extreme angle, subject cut off at the edges), say so early and lead with the reshoot recipe.
- Plain Australian English.
