Introduction: High Speed Coloured Ink Plume Photography

关于:摄影师(主要是肖像和野生动物)图形设计师

我从来没有做过任何与高速photography, let alone that of the fluid dynamics of coloured ink and oil in water. The best thing you should do before attempting a new project is to thoroughly research it, so you can learn from other people's mistakes, which is likely what you are doing now!

我没有。我有一个我想在我脑海中创造的形象,这是我完全试验和基于错误的刺伤,在尝试复制它!我已经包括许多试验测试和失败的实验,因此您不仅可以从工作中的工作中学习,而是没有什么,但是为什么。

I've been a fan of Instructables for a long time, but this is my first attempt at creating one! If you enjoy this I'd really appreciate a vote or a favourite, or if you didn't: some constructive criticism on what I can do better next time would be greatly appreciated. Thanks!

All images above are the final result, not stock photos! Hence I am extremely pleased with them and how they surpass completely what I expected to achieve.

第一步:为什么?

我是摄影师和平面设计师。我很喜欢但自己很少做的一些事情是高速摄影、流体力学摄影和近距离、抽象的色彩。

I was inspired for this project over the course of a day by a few things:

  • 我最喜欢的音乐频道CloudKid,利用挥舞着墨水模式作为视为可视化者,我不断怀疑他如何管理令人敬畏的艺术品!
  • 最近的视频,由Destin,来自Smarter Every Day,展示了两个墨迹漩涡高速相互射击。它本身既是科学又是艺术!
  • 放置的紫罗兰色食物着色。这是我的favouritecolour.I mean, cmon. I just had to do something cool with it!

第二步:容器

Fluid dynamics involves the interaction of two fluids. Seeing as I have no capability to work with gas, it was pretty obvious I needed a tank to hold my liquid.

在我寻找一个集装箱时,我持有以下标准:

  • 最小曲率(通过完全正方形的边或非常大的,因此是渐进的曲线。
    • 这是为了减轻内容的任何失真/鱼眼效应,从而使曲线上没有可能破坏图片的明亮高光反射。
    • 在我的搜索和测试中,我发现非常大的圆柱形管,由于更渐变的曲率,比较小的管更好地优于较小的管。
  • 没有雾化或品牌。
    • (An Airsoft BB bottle I debated using had embossed / pressed branding into the side, this seemed to be no issue until it was highlighted by the flash)
    • 即使是杯子和盒子的轻微雾气似乎也会显著降低清晰度。
    • Camera lenses can't focus fully up close (Well mostly, we'll talk on that later.) So the larger the container the closer the camera can be to the glass, reducing the reflection and allowing us to focus past it, whilst allowing us to focus clearly on the objective.

最后,我能够源是一个相对大的花瓶,这是一个粗糙的立方体,曲率最小。

理想情况下,一个DIY有机玻璃或真正的鱼缸将是更好的地方,这将是很长的,以允许在'大'的标准下讨论的细节。重要的是要注意,你使用的任何东西都必须是防水的!

在彻底洗涤后,我使用了Windex,以确保玻璃上没有污迹或可能导致人工制品。

用手擦拭填充罐的内部以去除气泡是至关重要的!从我的懒惰中毁了太多照片!

Step 3: Camera & Lighting (Gear!)

I use a mix of different equipment throughout, which I will cover here.

Photography Jargon:

相机是一个7D Mk1,用于它的显着高快门速度的相机在它的范围(1/8000)

我使用了24-70升,因为2.8 F停止。我实际上还利用了股票股,因为我有一个宏观附件,允许我直接抵靠玻璃柜,尽管图像质量因质量而明显差。(它确实通过实验与F32(而不是F22)有用,允许我实际上专注于一切,而不是强迫我使用ND过滤器)

我用了四盏灯。主要是上面的红色是标准的工作室灯,一般的大型'填充'光(灰色)和佳能速度石(580ex)。我用软盒配有光线,以扩散光线并填充完整的羽流,同时避免在Photoshop中无法删除的苛刻阴影。

I used a standard tripod which doesn't have anything special of note for this purpose.

如果这对你没有任何意义,你不是真的进入摄影,你仍然可以通过较慢的墨水和一个好的智能手机实现类似的结果!这里的难度正在实现非常清晰的图像,没有噪音(低ISO - 使用非常明亮的灯光)

到达的问题是,由1/8000快门速度捕获速度闪光灯(它被设置为高速模式超过1/250),但太快捕获从动模式上的其他灯光(当它们看到时闪烁闪光)。因此,我只是用它们作为填充灯(永久开启),以大多数消除当我闪烁的闪光灯时创建的阴影,并且它从玻璃和表格施放阴影。

All cameras that aren't SUPER high end or mirrorless use a rolling shutter, I think Vsauce's 'Distortions' has a good explanation on it. Hence 250 was about the maximum speed my shutter could handle when plugged into the other lights.Under that and an image like the last one above was created.

第四步:测试1!

我用一些食物着色糊(黑色)混合水,我可以承受浪费。如此,我可以在没有排空坦克的情况下进行许多重复,与墨水相比,我们以后创建的墨水完全污染了5秒的扩散。

为了做到这一点,在一个漆黑的房间里,相机处于灯泡模式(快门打开)时,我们从水箱下面闪动扬声器之前显示的设置,然后使用slave从上方(举起)闪动大的演播室灯光,所有这些都是在相机释放之前完成的。

Timing the ink from a pipette with the speedlite in pitch black in a tiny room with a camera that requires the shutter to be held down during bulb mode, was extremely awkward and wasn't working as well as I wanted.

主要是由于相机抖动,较大的ISO和不均匀/不一致的光与手臂的方式!

值得注意的是,尺子被放置在坦克的中间,为相机专注于参考点,这非常有用。

After this I knew that the idea would work, but that flashing the flash with the plume was not the way to go.

第5步:纯油!

I tried a setup with pure oil to see how it turned out. Again it was necessary to blend the hot oil in with food colouring in order to create a mixture which was then deposited underwater.

The results were underwhelming but had potential. I think a fluid (as discussed next) into an oil bath would be a lot better, but I did not have enough oil. I will have to try it in the future as I think results may be even better than my final main results!

Step 6: Violet Pastel!

After several iterations I found the best mix was very small amount of oil, a very high concentration (non aqueous food colouring) as aforementioned, and double cream. It was necessary to heat the oil to incorporate it, and it seemed to create some cool effects inside the plumes such as globular smooth balls rising up to the surface.

I prefer the solid dye to the liquid dye as due to the cream being over-saturated with it you can see solid chunks of it fall down / rise up from the plume trailing behind diffusing ink, which looks incredible.

第七步:新的设置!

I used many cardboard boxes to raise my container to the desired height and used paper to hide their colour, I used a softbox fill light on the side, and a fill light shining at the background (white screen) which eliminated shadow from the speedlite. The speedlite was camera mounted and shone directly up into a silver reflector which reflected it top down into the fluid.

使用侧面孔盒确保墨水铸造手不会延伸阴影。

为了拍照,我尴尬地躺在一边,手里拿着调焦环和遥控快门。当我把墨水滴进取景器时,我调整了焦距,用手指笨拙地按下了快门。

我觉得铰接屏幕会在这里非常方便,但结果还好!

在水下创造时,我发现羽毛更好,并且闪光灯设置为“多”,所以我可以获得每墨水羽毛的至少5次闪光。我没有做到这一点,以避免在已经灼热的房间里过热!

我尝试了f32镜头,快门速度更低,灯光更暗,试图获得一个羽状物在全焦,但许多人工制品也被拉到焦点。因此,我建议在Photoshop中人为地锐化东西,而不是使用更高的f停止。

最初的结果是非常令人不快,所有的焦点和模糊。我知道这个错误是人为的,每次都不一样,所以我用了一个遥控快门,并提高了f停止,以减少人为造成的模糊。我一直坚持,直到我得到了一些好的结果,然后我坚持这样做!

这套结果非常好。我重新填充并恢复了每种墨水矿床之间的罐并继续。

I collected my final photos (which were all taken in RAW (never shoot jpg when you're doing intentional, planned shots you plan to edit!) and separated out the best ones for editing.

Step 8: The Edit.

编辑包括在Lighroom和Photoshop中重复几个步骤:

One Time:

  • Set white balance to the background and mask off where the effect is not satisfactory (small fibres)
  • 调整曲线以较低的黑色并稍微抬起亮点

Repeat:

  • 中途提升清晰度和清晰度。
  • 增加噪波滑块以减少添加的噪波
  • Increase exposure very slightly to compensate for added clarity
  • 增加突出显示以弥补清晰度
  • 稍微减少或增加很多,阴影,取决于什么适合更好。

使用径向过滤器重复较少或更强烈的。

然后我用过照片脱离上述诅咒的气泡!Lighroom的现场愈合刷工作,但不是光滑工具的组合

  • 混合刷10%
  • 现货愈合工具10%
  • Clone stamp 75%
  • Brush tool 5%

带有克隆图章的专业提示是在变亮和变暗之间交替进行,以消除眼睛立即发现的虚假或可疑的重复图案。

您甚至可以使用色调调整来将颜色更改为整个Rainbow Spectrum!可以使用Lightroom(Color独立)或刚使用Photoshop中的面具(需要年龄段!)来进行更小但更准确的更改。

第9步:最终结果!

I'm very happy with the final results of my violet ink plumes. Next time I'd love to experiment with vortexes and utilising hydrophobic materials a lot more.

我认为半混合染料可以创造一些奇妙的看起来像我从CloudKid的灵感艺术一样漂亮看起来像我的灵感艺术,但我很高兴我选择了我的主要颜色作为紫罗兰色。
