拍摄建议

以下为 FilmAnalysis 编辑的拍摄经验,不是资料来源中的内容。

满树白花要在阴天或柔光下拍,才能保住花瓣层次,减半档;近拍时紫红色的花药是白花里唯一的色点,微距对准它。梨园成排的白花配上远山用长焦压缩;日本梨园的棚架结构本身就是几何题材。

适合的摄影风格

满树雪白的春日;紫红花药的微距。

相似物种

白梨、秋子梨(北方的梨,花相似,叶和果不同);苹果花(带粉色,花药黄);李、樱(花药黄,花梗不同)。

Identification

A deciduous fruit tree with ovate leaves edged with bristle-tipped teeth. Flowers in spring before or with the leaves, white five-petalled, six to nine in umbel-like racemes with purple-red anthers, the whole tree white; the round brown or yellow speckled fruit is the sand pear or nashi, grouped with the cultivars of other species as the Asian pear.

Habitat

Orchards, village surroundings, hillsides and river valleys, widely cultivated, wild in the hills of southern China and northern Indochina.

Distribution

Native to southern China and northern Indochina and introduced to Korea, Japan and the rest of the world; widely grown south of the Yangtze in China, and Japan is a major pear region (Tottori's Nijisseiki, Chiba and others); absent from Singapore.

Season and behaviour

Flowers in March and April for about a week, around the time of the peach; fruit from August to October.

Photography tips

These are the FilmAnalysis editors' notes, not content from the sources.

A tree white with flowers needs cloud or soft light to keep the petals' detail, half a stop under; close up the purple-red anthers are the only colour in the white flower, so the macro aims at them. Rows of white in an orchard compress against distant hills with a long lens, and the trellis structure of a Japanese pear orchard is a geometric subject in itself.

Photographic styles

A spring tree white all over; macro of purple-red anthers.

Similar species

Pyrus bretschneideri and P. ussuriensis (the northern pears, similar flowers, different leaves and fruit); apple blossom (pink-tinged, yellow anthers); plum and cherry (yellow anthers, different pedicels).
