在现今几乎是人手一台智能手机的情况下,拍照已经是一件非常容易的事。但是,笔者还是时常在逛论坛的时候看到不少被照得很模煳的照片。最令发文者与阅读者沮丧的莫过于尝试自模煳的照片中辨认手錶的细节。当然,当拥有适当的打光器材以及不错的相机,其实要照出模煳的照片反而是更困难的事情,但是不是每一个人都能拥有那样的器材。幸运的是,其实你用智能手机就有可能照出媲美摄影棚品质的相片。笔者在这边就分享一些小技巧,让各位也能用智能手机帮自己的手錶照出漂亮、清晰的照片,并可以自豪地展示给其他人。

目标很简单,就是:帮你的手錶照出不经任何后制(例如使用Photoshop或是其他软件来修图)、直接就可以上传使用的照片。你所需要的就是一台智能手机,当然还有你的錶。

照相最重要的就是光线。笔者甚至可以大胆地说:摄影其实就是对光线的控制。如果你要有一张清晰的照片,你首先要确定的就是你的主体能被足够的光线照到。足够的光不但可以让相机能捕捉到更多细微的细节,也可以减低快门时间(所以减低手震的机率)。有些人会推荐闪光灯,不过那需要一些时间学习才能上手。笔者给业余者的建议是:阳光是你最好的朋友。阳光是一个强烈却不需要额外散光设备的光源,最棒的是,它是免费的。你可以选个晴天,然后开始在不同的时间点试验来找到你要的感觉与结果。请注意,照相的时候最好避免让自己的影子打到你所要摄影的主体上,或是让强光直接反射进你的相机镜头。以个人习惯而言,笔者通常会避免在中午拍照,因为在照俯视图的时候,很难避开自己的影子。



在取得光源之后,第二件要搞定的就是你的智能手机。一般人在拍局部特写最常犯的错误就是照相的时候,把手机靠得主体太近。这当然是可以理解的,因为人们倾向把画面用主体填满,而不是留下大量的空白背景。但是一般智能手机通常都有个最短对焦距离,这距离通常比你想像的来得长。当然你可以靠后制把多余的背景给剪裁掉,但是这已经超出本文所要讨论的范围。



如果你的智能手机有近拍模式(通常是一个小花图示),请开启它。如果没有,也没关系。先将你的手机往后移动,直到你的手机能够正确地将画面正中央的物体对焦(通常会有一个绿色框显示)。一旦对好焦之后,用两只手指在触摸屏上分开(或是用拉近按钮,比如说音量增强钮,如果你手机有的话)来将整个主体拉近。你将会发现你要摄影的主体能在不失焦的情况下被放大。当你对于构图跟对焦都感到满意时,再按下快门键。不同的守机会有不同的设定,但是大致上都一样。你可以尝试使用不同的设定(比如说HDR)来取得更佳的效果。

如果你想尝试用其他软件进行后制的话,请用最大的像素设定来得到更好的后制成果。如果你只是要直接上传图片的话,你可以选择中等的像素设定来得到更快的上传速度。

现在,让我们来总结一下重点。
1. 挑一个晴天。不要把自己的影子盖到主体,或是让光线直接反射进入相机镜头。
2. 不要把智能手机靠得离主体太近。在将画面拉近之前,请先确定相机已经对到焦。
3. 选择适当的输出像素。如果你要直接将图片上传到网路上,尝试透过像素设定来将影像大小控制在1MB左右。
4. Good luck, have fun!

Taking pictures is an easy thing to do as almost everyone has a smartphone with camera capability nowadays. However, I often see blurry pictures when I browse through online forums. Nothing is more frustrating for both the owner and viewers trying to identify a watch with only blurry pictures on hand. Of course, with proper lighting equipment and a decent camera, it would be even more difficult to take a blurry photo, but no everyone has access to those. Fortunately, it is possible to take studio-like pictures of your watches just using a smartphone. I am here to share a few tips so everyone can take nice, clear pictures of watches using just his smartphone and proudly present them to the world.

The goal is very straight forward: to take ready-to-upload pictures of your watches without any post processing (e.g. using Photoshop or other software to enhance the image). All you need is a smartphone and, of course, your watches.

The single most important thing in photography is lighting. I would even go as far as saying photography is all about manipulation of lights. If you want a clear picture, the first thing you want to make sure is that the subject receives sufficient light. Stronger light not only enables the camera to capture more details of the subject, but it also decrease the time needed for the shutter (thus, lower the chances of unsteady hand effect). Some people would recommend an electronic flash unit, but it takes some time to master. For amateurs, I would say natural sun light is your best friend. It is a bright light source that does not require extra diffusing equipment, and the best of all: it is free. You can just pick a sunny day and experiment with different time of the day to get the result and the feel you want. Please note that you might not want to cast your own shadow onto the subject or let the lights reflect directly into the lens. Personally I would avoid noon because of it is difficult to take top pictures without casting my own shadow onto my subject.



Once you got the light, the second thing you want to conquer is your smartphone. The most common mistake people make when using their smartphone to take close-up pictures is that they hold their smartphone too close to the subject. It is understandable because people usually that the subject to fill the whole screen, but not just a small part of the picture. However, most smartphones have a minimum focal distance that is usually longer than you would expect. Of course you can take a large resolution picture and then use other software crop the extra background off, but that is out of the scope of this article.



If your smartphone has macro-mode (usually indicated by a flower icon), use it. If not, do not worry. Just move your smartphone back until your smartphone can focus the subject that is in the middle of the screen (usually indicated by a green square). Once the subject is in focus, try to zoom-in by touch the screen with your two fingers, and then split outward (or a zoom-out button like volume+, if you phone has one). You will see the subject remains in focus while getting larger. Just click on the shutter when you are satisfy with the composition and focus. Different phones have different settings, but it is generally the same. You can just play with different settings (such as HDR) of your phone to get better results.

If you plan to use other software to edit and shrink the pictures afterward, take pictures with the maximum resolution to get better editing results. If you plan to upload the pictures directly, then choose medium sized picture resolution for faster upload.

Now, let's summarize the key elements.
1. Choose a sunny day. Do not cast your own shadow onto the subject or let the lights reflect directly into the lens.
2. Do not place the smartphone too close to the subject. Make sure the subject is in focus before zooming in with the touch screen.
3. Choose the right output format for the pictures. If you plan to upload the picture directly onto the web, try to limit the file size under 1MB each by adjusting the picture resolution.
4. Good luck, have fun!

The follow images are taking by entry level smartphones retailed under USD$150. All images are taken using built-in camera software without any post processing (i.e. uploaded directly from the phone).
