The film sheets measure 4x5 inches (approximately 10.2 x 12.7 cm).

Check for light leaks in your camera or film holder. Ensure the film was loaded correctly with the emulsion side facing the lens. Consider recalibrating your light meter.

While HP5 Plus has fine grain, extreme pushing or aggressive development can increase grain. Ensure you are using appropriate development times and chemicals for the desired ISO. Consider scanning at a lower DPI if grain is an issue for digital output.

This could indicate exposure to light during handling or storage. Ensure film is stored properly and handled only in dark conditions. Check that stored film is not too old, as degradation can occur over time.

Ensure your camera lens is clean and properly focused. Check that the film plane is parallel to the lens plane. For large format, be mindful of the shallow depth of field and use appropriate focusing techniques.
