Description

今回は一番利用度の高い３５ｍｍカメラをモデルにしました。３５ｍｍその他、大型カメラを含め被写体がレンズの光点を中心にカメラ側の感光材（フイルム）等に写る訳ですが３５ｍｍを（例）にすると面積は２４×３６ｍｍ…大型カメラのフイルムサイズもそれぞれの大きさから成りたっている事は一般的な社会の常識です。This time, I used the most popular 35mm camera as a model. In addition to 35 mm, the subject is photographed on the photosensitive material (film) etc. on the camera side with the light spot of the lens including the large camera, but if 35 mm is (example), the area is 24 x 36 mm ... film size of the large camera It is common sense in general society that it consists of the size of.

そこで２４×３６ｍｍを方眼紙に平面図を書き、それに対角線を引くと中心点が光点になる。その光点より上下、左右に縦線と横線を引きフイルム外側より内部図面に縦と横の線を引き対角線と交わる縦、横の点…又同じ方法でそれより内側に２〜３ｍｍの同様な線を引く…外側と内側には当然長さの違いが出る。Therefore, a plan view is drawn on a 24 × 36 mm grid paper, and the center point becomes the light spot if the diagonal is drawn. Vertical and horizontal lines from the light point vertically and horizontally, draw vertical and horizontal lines from the outside of the film, draw vertical and horizontal lines in the internal drawing and intersect diagonal lines ... or 2 to 3 mm inside from the same method Draw a line ... Of course there is a difference in length outside and inside.

そこで、内側の縦と横の中心点を原点とし外側の線に何ミリかの斜線を引きますと（別紙図面のような△▽が出来ます）大型サイズも同様です。So, if you draw a few diagonal lines on the outside line with the center point of the inside vertical and horizontal sides as the origin (the △ and よう like the attached sheet drawing can be made), the large size is the same.

材質は硬めの部質（例）樹脂製、１〜２ｍｍの厚さ、色は薄目から〜ある程度濃いめが必要です、艶消しで半透明を使用、色はさまざま…Material is hard texture (example) made of resin, thickness of 1 to 2 mm, color should be light to dark to some extent, use matte and translucent, various colors ...

加工方々はプレス式や型に流し込み式を、その他（形は別紙平面図に記載）△▽の△の部分を残し▽と角の部分をカットする。その部分は空洞になり入射光として被写体が感光面に写る。The processing people cut the part of 角 and the corner, leaving the part of △ and その他 of その他 and others (the form is described in the plan view of the separate sheet) in a press type and a mold. The portion becomes hollow and an object is reflected on the photosensitive surface as incident light.

（平面図）図１．図２型は周辺ぼかし用に、図３型はこれから、ます々高齢者が増えいろ々な面で人物写真が必要な時、車椅子等の下側、左右をぼかした写真の撮影が出来ます、図４型は接写用レンズに使います。(Plan view) FIG. Figure 2 type is for peripheral blurring, figure 3 type is from now on more and more elderly people are increasing and when it is necessary to take portraits in various aspects, it is possible to take pictures of the lower side of the wheelchair, etc. Figure 4 type is used for close-up lens.

フィルター外観はネジ込みを採用、被せ式、バヨネット式等がありますがフィルターの前にフードを取付ける関係からもネジ込みがよい、尚フードは広角の利用を進めますフードで四隅がケラれる可能制がある為、又ネジ込みは工程上の面からも、コストの面からもよい。The filter has a screw-in, cover-type, bayonet-type, etc., but the screw is good because the hood is attached in front of the filter, but the hood promotes wide angle use. Since there is also a screw-in process, it may also be cost-wise.

使用方法、アップで絞り込みは浅めで撮影するのが一番良いと思う。被写界深度の関係上絞り過ぎると波型の形が出る恐れあり、どうしても絞りたい時は絞りを階段式で何コマか撮影…レンズは標準より長い望遠レンズがよい。How to use, I think that it is best to shoot in a shallow and narrow down in the up. Due to the depth of field, there is a risk that a wave-like shape may appear if the aperture is too large. If you really want to stop the aperture, take a few steps on the aperture. A telephoto lens longer than normal is better.

試作品による実写撮影。三脚にカメラを固定しフィルターなしと、フィルターを取付けた状態で撮影、ぼかしフィルターを使った場合、周囲の余分な所がボケ写す部分が強調されます。レンズニコンズーム３５ｍｍと１０５ｍｍで撮影…見本写真（裏側に撮影データ記入）Live-shooting with prototypes. If you use a blur filter with the camera fixed on the tripod and no filter, and with the filter attached, the blur in the surrounding area will be emphasized.

Claims

The material of the filter is made of plastic and semitransparent material, and the object is not reflected on the photosensitive surface when the semitransparent resin remains, so the camera filter is punched in the waveform with the center of the filter as the origin.
