The human iris is not only beautiful, but it also looks otherworldly. That’s why macro pictures of eyes are so interesting. 这是如何在一个简单的宏观眼影教程中拍摄眼睛。
使用宏观镜头保持清晰度
Regular lensesaren’t good for taking宏观照片. They only work up to a certain distance to produce a sharp image. When it comes to eye close-ups, the best option for you is to use a宏观镜头. This type of optics allows you to “zoom” into your subject up closewithout losing sharpness. 最好的微距镜头拍摄照片的眼睛should have a焦距至少100毫米。它具有理想的长度，即使你远离你的主题，让你也会让你接近。 请记住，保持距离很重要，因为如果你太近了，你可以阻挡击中学生的灯光。
您可以使用的宏观镜头替代品
你可以使用替代品，如波纹管,延长管， 和逆转戒指instead. 这些附件中的大多数都没有超过20usd，它们很容易使用。你所要做的就是将它们附加到常规镜头上，你自己得到了一个转换的宏观镜头。 You can use your macro attachment to any lens. But it would help a lot to choose the longest lens you have. That way, you don’t have to get too close to your subject. 宏附件的唯一缺点是他们经常禁用镜头的自动对焦。这意味着您需要手动调整焦点戒指以获得锐利的图像. But that’s a small price to pay as compared to buying an expensive dedicated macro lens.
宏观眼影的相机设置
生产神奇的宏观照片的眼睛不结束使用宏观镜头。您还需要确保您有正确的相机设置确保您获得最尖锐的图像。 Below is a list of our suggestions.
Your lens’景深(the area in focus) gets smaller once you start shooting macro. To help you lock in your focus better, you’ll need to use the properAperturesetting at all times. 避免使用诸如F / 1.8的大孔径。它的浅景深即使在你近距离接近，你也会让你更难以捕获敏锐的形象。 相反，使用窄孔，例如F / 8或F / 11，以增加您的景深。请记住，由于您拍摄宏，无论您使用的设置，景深仍然很小。 但是选择一个狭窄的孔径使焦点区域变宽，以使您更轻松。
快门速度
For the most part,快门速度与宏观摄影的光圈不那么重要。ayx大小因此，请随意使用光圈优先，让您的相机选择快门速度automatically. It will save you a lot of time and effort tinkering around. 尽管如此，您仍然应该让它在拍摄前检查快门速度的习惯。 Make sure it doesn’t go below 1/60th of a second. Especially since anything slower than that value can cause运动模糊and ruin your image. 但是如果摄像机选择的快门速度低于1 / 60th，该怎么办？然后考虑添加灯以增加曝光。 If you’re using an aperture of f/11, you can lower it to f/8 to let more light in. You can also try bumping up your ISO. As long as you don’t go beyond 800, you shouldn’t worry too much aboutimage noise.
Let the Eyes Rest to Minimise Redness
巩膜或眼睛的白色可以敏感。如果它经历过大的压力，它可以变红，可能会在图像中看起来很丑陋。 If you want to include the sclera in your macro shot, make sure your subject has adequate rest. It doesn’t mean you should ask你的模型在拍摄前睡觉。告诉他们不要做可能会留下眼睛的活动。 这包括盯着他们的电脑或电话屏幕。 如果你仍然看到巩膜中的微小静脉，请使用逆耳的眼睛滴剂来减少发红。 只是注意不要经常将它们应用于你的主题。长期使用滴眼液会引起刺激。
保持您的主题仍然避免丢失焦点
当您拍摄宏观照片时，您会意识到即使是轻微的运动也可以抛出焦点。这就是为什么保持你的主题和你的相机仍然是至关重要的原因。 So how do you ensure your subject doesn’t move while you’re shooting? The easy answer is to ask them to lie down or to sit. 确保它们舒适，并且它们有足够的颈部支撑，以防止它们移动。 It would be best to set up your camera on三脚架保持它稳定。一旦你的主题休息，重点盯着你的镜头并记住你的距离。 You should place your tripod at the same spot, so you don’t have to adjust device every time you take a photo. 您还可以选择使用aremote trigger脱掉相机。这样做可以防止您触摸您的设备并在按下快门后可能导致运动模糊。
How to Light Macro Pictures of Eyes
灯光在创造眼睛射击时至关重要。您需要确保您在明亮的区域拍摄照片，以捕获您受试者虹膜的所有细节。 It would also help a lot if you choose a spot where the catchlight is good. 录制灯是指互补眼睛的光源。它通常像虹膜一样圆形，并在眼睛内显示为明亮的结构。 有许多不同形式的录制灯。它可以是来自太阳甚至是灯泡和闪光灯的天然光。
Natural Light
在大多数情况下拍摄眼睛时，这种形式的照明效果很好。我们不建议您在直接的日光中拍照，因为它可能会损坏您的主题的眼睛。 但是你可以随时寻找一个大的阴影区域视窗. These will provide you with the right mix of阴影和镜布亮点以捕获这些细节。
These aren’t the best choice since they cause a lot of people to blink. But they’re surprisingly good at illuminating the eyes because they’re quite powerful. Just remember to use low power when you can, so you don’t blind the subject with the light burst.
灯光Direction
You should also place your光源到了一边，而不是将它放在相机顶部。这样，长镜头不会阻挡光线并延伸丑陋的阴影。 如果你不想要怎么办catchlight反映了虹膜？然后将光源直接放在眼睛旁边。 它仍将亮起眼球，但没有任何镜面亮点。 当你在你的主题附近放置光源时，请让他们闭上眼睛，直到开始射击。这样，亮度不会导致它们不必要的应变。 但是你也不应该在你的主题打开眼睛后立即按下快门。 给他们一些调整的时刻。一旦注意到他们不再眯着眼睛，就会随意拍照。
Edit Your Macro Eye Shots to Bring Out Details
如果你做得正确，你的眼睛特写应该看起来很令人惊叹。但是你可以让它更加迷人editing it in post. The first step is to adjust your basic settings. If the color cast on your image looks unnatural, feel free to play around with your white balance. 当你觉得颜色are finally spot on, tweak your Exposure slider to make your image bright enough. Then, increase your contrast to make the details look prominent. Next, adjust yourhighlights and shadows. Doing so brings out the depth of the iris. You can also change the Black and White level to fine-tune the image’s contrast. 最后，使用振动和饱和度带出你眼照片的颜色。只要保持调整中等，因为你不想结束不自然的色调。
把巩膜淘汰出局
有时，即使使用具有长焦距的宏观镜头是不够的，无法靠近虹膜。 If you zoom all the way and still see the sclera, then think about cropping it out in post. This technique allows you to “zoom in” closer to the eye by clipping out parts of the image. All you have to do is use the crop tool to reframe your shot. Feel free to use the grid to recompose your image. 当然，你并不总是必须将虹膜放在中间。您也可以尝试其他组合物。 只需记住不要过度，因为它会影响图像的质量。 The more you clip out of the picture, the more grainy and pixelated it will get. So get rid only of the parts you don’t need.
结论

When you have the perfect light and focus, you can expect great results. So go ahead and try it. See what it’s like to look at the windows to the soul up close.
