简介:Bokeh Kit

"In photography, bokeh is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as "the way the lens renders out-of-focus points of light". Differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting—"good" and "bad" bokeh, respectively. Bokeh occurs for parts of the scene that lie outside the depth of field. Photographers sometimes deliberately use a shallow focus technique to create images with prominent out-of-focus regions." (obtained from https://en.wikipedia.org/wiki/Bokeh)

Bokeh is a really cool effect when used properly and something that most photographers have tried or actively use and is especially popular with photography enthusiasts all over the world.

这项技术的一个巧妙的副作用是,如果你在背景上有灯光,这些灯光就会变得模糊,变成一个大光圈(所包含的bokeh照片的所有学分都归用户SumbO,在http://7-themes.com/6870065博凯摄影馆。。。但你并不局限于这个形状。由于镜头的形状,这些大圆是圆的,是圆形的,所以如果你限制光线进入并强制它变成另一个形状,那么一张背景上有灯光的正确制作的bokeh照片就会有这个形状,进入bokeh工具包。

I've seen several bokeh kits for sale and some diy ones, but none of those was very appealing, I really didn't want to use rubber bands on top of piece of cardboard it just seems to cumbersome, what I wanted was bokeh kit that I could easily clip-on the lens with a single hand, something that was sturdy enough for repeated use and something I could easily create new shapes for.

Well I have a 3D printer and I know how to make 3D models so it was time to design something. I went with Fusion 360 for this design so that I could take advantage of the parametric design, this should allow me to easily to scale the model to different lens sizes and in fact I did just that, I modeled this for a 52mm lens and afterwards scaled up for a 55mm lens and I only had to change to drawings, how awesome is that :).

P、 这是一次很好的学习经历,因为这只是我第二次在Fusion 360中建模。

Step 1: Basic Shape

First things, first, dimensions, I wanted something to clip over the lens, so I measured the lens I had, a 52mm, and after adding a 0.4mm to ensure a snug but not overly tight fit, I had 54.60mm, which I then offset by 1.7mm, this was simply eyeballed, I just need something thick enough to be solid and you could probably get away with less.

我挤出了外圈10mm,然后将内在的内部挤出5.5mm,从而切割那块较大的圆柱,再次我只是用它的粘合它。

Step 2: Lens Openning

接下来是时候打开一条光线进入镜头的路径了,所以我在设计的中心画了一个35毫米的洞,然后把它挤出。

第3步:裁剪形状

我可以简单地在我已经拥有的设计上做出我想要的形状,但是我决定我想要一个模块化的东西,它不会占用袋子里太多的空间,所以我决定也为这些形状创建一个夹式设计,任何人都可以很容易地打印和制作,即使他们不知道如何制作模型。

The measurements provided in the pictures were once again roughly made, I just went on to sketching on the surface of the design for a shape that could easily be clipped on the bokeh kit, when that was done I extruded that shape out by 2.5mm. At this point I was considering a collection of different shapes so I need a clip-on shape that was really thin to maximize the number of shapes that I could make and carry and minimize the plastic I would have to spend.

第4步:制作插槽

I had the space for the clip-on shapes, I now had to make a slot through which they would slide into the design, so I offset the space I had just make, by 0.8mm and then extruded out that shape by 1.18mm (you guessed eyeballed it again :) ). I now had a slot, but also had a tricky overhang and I hate those, so chamfer to the rescue, I chamfered the overhang by 0.8 to coincide with the 0.8mm offset from before and the slot was done, I could easily be printed and I had roughly a 1mm thickness for the clip-on shapes.

第5步:将散景剪切到镜头

在继续之前,我真的需要解决我的主要问题,如何剪辑波基镜头安全?我已经有了一些使用小螺丝钉的bokeh套件,但对这种设计不满意,金属螺丝可能会损坏镜头塑料螺丝钉使用时间不长,所以我需要其他东西。我用了两个侧夹,它们有一个小杠杆供你压,这足以打开夹,从而允许快速和容易的拆卸/安装,因为这是在一个单件印刷,没有必要挑剔的组装。

所以我在设计的底部勾勒出这个设计,但我仍然需要切割夹子的一点空间来延伸和抓住镜头,所以我制作了一个11mm的高度矩形,然后用5mm挤出设计,然后用5mm挤出设计。然后我继续挤出将它们加入套件的剪辑10毫米

Step 6: Perfecting the Clip

此时,我决定将倒角添加到实际抓住镜头的作品。这一步骤可能没用,但我的推理是,在那篇文章的顶部,切片机生成的任何支持都会删除,所以如果我可以最小化我将最小化。

第七步:完善工具箱并制作夹子

在这一点上,模型看起来几乎完成了,但我不满意的入口通道,剪辑形状将进入。我选择在上面剪一点,这样既便于打印,也便于插入形状。
下一个是夹上的形状,我已经有了基本的形状,我之前偏移了0.8毫米,所以这次我又偏移了0.2毫米到里面。然后,我继续创造一个小把手,将略有突出的套件,使其易于拆卸,并确保它不会刹车,我适用于一个圆角的基础上,它的一部分,从而使它更强大,减少苛刻的你的手指。

我可以留下这样的设计,打印公差应该确保剪辑会有效,但如果重复使用这一点,这将失败,所以我选择了一个小弹簧,使其成为一个艰难的弹簧。我简单地在厚度1毫米的侧面切开了一个槽,并在夹子外部添加了1mm半圆,这提供了弹性,以确保夹子会保持夹子。

因此,与形状勾勒出所有需要的是一个1毫米挤压和基础设计的剪辑形状完成。

第八步:发挥创造力

现在设计完成了,我所要做的就是做一些很酷的形状并开始拍照。我已经准备好了一堆的形状从我的其他尝试在一个bokeh工具包,其中一对是在inkscape的其他人是从字体,如Wingdings和它的变种,或字体真棒。我只是简单地导入了图纸,居中并将它们挤出了剪辑形状,就完成了。现在我需要打印并测试它。

步骤9:打印和测试

我用PLA打印了Bokeh套件,220ºC(这是BQ PLA,这是推荐温度),0.2mm层高,3个周边,15%填充和支撑。我不喜欢需要支撑,但我真的没有想到避免它的想法,最后我刚刚诅咒他们在那里被使用,如果我们需要它们,这种设计需要它。

形状上的剪辑被打印出完全相同的设置,总的来说,大约需要两个小时才能打印整个套件。

在这一点上,我有一个小问题,我仍然没有买单反:P,但我有一个旧单反,所以我检查尺寸是当场。下一次测试,我仍然没有接触到单反相机,但我知道有人,所以我把它给了一个朋友,测试,并确认它的工作,事实上,他非常喜欢,我做了几个额外的形状给他。所以圣诞节来了,看我现在有一个单反,它不是我的,但我可以玩它(谢谢姐姐),这一刻,我看到它不适合,但为什么?简单的镜头是55mm而不是52mm dohh,所以参数化设计拯救简单地增加3mm额外的初始设计,移动剪辑3mm,导出设计和打印它。

因此,请为您提供一张您可以通过此检查所包含的图片(由User MK82 Over over:

所以对于你的焦外成像设备需要的设计,one for 52mm and the other for 55mm.

52毫米

55毫米

PS This design should fit a many lens but I can't guarantee that it will fit every single one out there.

    谢谢你的评论。我不是询问摄影的理想人员,而是应该用大多数镜片制作散景摄影,但看物理可能取决于散景形状和它通过多少光。我认为,对于某些镜头尺寸,您可能必须使中心形状更小或更大,不幸的是我没有足够的体验来真正帮助。

    对于想要拥有这些套件之一但没有3D打印机的任何人来说,请查看最近的图书馆或制作空间,看看它们是否有一个可供公众使用的3D打印机。替代地,您可以结账3Dhub,它不应该'太昂贵的订购打印。

    好主意。从塑料板或卡片上切下“过滤器”并使用cokin支架将不得不为我做这些,因为我无法使用花哨的3d打印机或激光切割设备。

    I've made a bokeh lens with my printer, not with this tutorial but it looks similar. But I got not get the bokeh effect to work... could this only work in certain settings or on specific lenses?

    已经使用'科金'过滤器多年(前数字)和我刚刚开始在三维打印,这看起来非常有趣。

    I have just started 3D printing and have enjoyed reading your explanation of the design steps, particularly of the more complex holder design. Actually, I think this is the first practical 3D print design discussion I've seen. Thanks a bunch!

    我从来没有听说过Bokeh,所以我今天学到了新的东西,认为这是一个很酷的解决方案,可以帮助完成工作。一个建议,如果您可以访问激光刀(或者知道附近的某人或本地制造商的某人),您可以激光从不透明的丙烯酸切除刀片,这可能比3D打印更快,更便宜。

    太棒了。能够使这些自己将节省你比购买商业版很多钱,你可以个性化他们使一些完全独特的。
