Architecture & verticals

The constraint is keeping straight lines straight. Ultra-wide lenses exaggerate any tilt: point the camera up at a building and the verticals converge like a cartoon, point it down and they splay. The fix is discipline — keep the sensor level, using the a6700’s level gauge and grid, so the walls stay parallel. Shoot aperture priority at f/8 for edge-to-edge sharpness and ISO 100 for the cleanest file, and let the 10-20mm swallow a whole facade or interior from a realistic distance.

Watch out for the compromise of a level camera: you often include a lot of foreground you do not want. Compose to use it — a plaza, a reflection, a leading path — or shoot a touch high and level, then crop the bottom. If you must tilt to fit a tall building, do it deliberately and fix the convergence in editing, where a wide, high-resolution file gives you room to correct.
