1. Chinthu chimodzi, zomanga zozizira, zitha kugwiritsidwa ntchito ndi kutsuka, kugubuduza, kukwapula, etc.
2. Itha kugwiritsidwa ntchito ponyowa (palibe madzi owoneka bwino) kapena malo owuma, ndipo zokutira ndi zolimba ndipootanuka kwambiri.
3. Ali ndi zomatira kwambiri m'maso, matope, konkriti, chitsulo, bolodi la thonje, otuwa, etc.
4. Chogulitsacho sikuti ndi poizoni, zopanda pake, zokhala ndi zachilengedwe, ndipo zili ndi zowonjezera,kunenepa, zomatira ndimawonekedwe opanga filimu.
5. Mtundu wambiri ungakhale. Red, imvi, yamtambo ndi zina zotero.

1. Chithandizo cha Pamtunda: Pamwamba pamunsi iyenera kukhala lathyathyathya, yolimba, yoyera, yopanda madzi osaneneka ndipo palibe kutaya. Ming'alu m'malo osasinthika iyenera kuchepetsedwa, kutayikira kuyenera kumalumikizidwa koyamba, ndipo ngodya za yin ndi yang iyenera kuzunguliridwa;
2. Kukuta ndi maburuki, malinga ndi njira yomanga, osanjikiza ndi mawonekedwe a → Zovala zopanda nsalu →
3. Kuphimba kuyenera kukhala yunifolomu momwe mungathere, popanda kuwonekera kwanu kapena kunenepa kwambiri kapena kunenepa kwambiri.
4. Osapanga pansi pa 4 ℃ kapena mvula, ndipo osapanga malo otetezeka komanso opanda mpweya, apo ayi zimakhudza mapangidwe a filimu;
5. Pambuyo pomanga, ntchito zonse za polojekiti yonse, makamaka maulalo onse, ziyenera kufufuzidwa mosamala kuti tipeze mavuto, pezani zifukwa zake ndikukonza nthawi.
Sungani mu malo ozizira, owuma, ofunda amtundu wamnthere pa kutentha kwa 5-30 c;
Nthawi yosungirako ndi miyezi 6. Zogulitsa zomwe zimaposa nthawi yosungirako zitha kugwiritsidwa ntchito pambuyo powunikira.
