Write down the location, likely light and two or three intended subjects. A short walk to photograph building details has different requirements from a family picnic that continues into evening. Begin with the camera and the lens most likely to make those pictures. Every additional item should solve a problem you can describe in a sentence.
Separate essential redundancy from speculative options. A charged spare battery may protect the whole outing, while a third overlapping lens may only offer a slightly different framing. A spare memory card occupies little space but should still be compatible and known to work. Do not remove small items that prevent a complete interruption simply because you are trying to minimise the item count.
Use evidence from previous outings
Look at photographs from a similar trip and identify which focal lengths or accessories were actually useful. This is evidence, not a rule that forbids experimenting. If you deliberately want to try close-ups this time, the macro accessory has a clear purpose even if it was unused before. The distinction is between a planned experiment and an item packed because it happens to be available.
Consider the consequences of leaving something behind. Without a tripod, you may accept a higher ISO or choose a different night photograph. Without rain protection in wet weather, the consequence can be damage or an early end to the outing. These are not equivalent compromises. Match the kit to the conditions you can reasonably anticipate and check local weather near departure.
Pack the reduced kit and carry it around indoors for ten minutes. Notice whether the bag interferes with a coat, whether the strap is comfortable and whether you can reach the camera without setting everything down. Weight on a list is less informative than how the load behaves on your body.
After the outing, record one item you were glad to have and one you did not use. Leave room for a genuinely missed photograph, with the equipment that would have enabled it. Over several trips this creates a specific packing history. The aim is not to prove that less is always better, but to make room for attention, movement and the equipment that earns its place.
