In addition, there is a mandatory supply of batteries, a polarization filter, thanks to which I can better bring out the beauty of clouds or rainbow in the sky. A good polarizing filter is also useful in the forest, especially wet from fog or rain – it allows you to reduce the reflection of light from wet leaves, making the image more saturated and effective. It is also useful to have a half gray filter with you to reduce too much contrast between the bright sky and the darker landscape below.
Less necessary, but sometimes also useful are the ND 1000 or ND 500 gray filters, which, by extending the exposure time significantly, allow a more artistic presentation of clouds flowing in the sky or water in mountain streams. Currently, mirrorless cameras, which additionally have a built-in stabilization in the body and great opportunities for shooting at higher ISO sensitivities, can sometimes cope with the lack of a tripod, but in the case of an ordinary SLR or in the case when a long time is necessary to achieve the desired effect – you should attach to the backpack also a stable tripod. However, there were also such days, especially in winter, when the wind was so strong that it knocked me over with my backpack, so there was no question of taking a tripod. Back then, the only solution was to set a high ISO and take handheld photos. Winter is generally snowy and demanding in the mountains. High snowdrifts can be found here when there is no snow at all in other parts of Poland. Then you may need snowshoes or, if the trail is icy, crampons.
