Yup I'm only using f2.8 because I do not have any flash with me except the one inbuilt in the 7d so I did not use a higher Aperture..
If at 1:1 (30cm) with f2.8 is not giving you enough DOF, 2:1 with f2.8 will be much worse. What you need is to use a much smaller aperture to get more of your subject in focus.
Ic, I just started macro I do not have the proper equipment yet. Any affordable flash to recommend for macro?Originally Posted by Schmike
2.8 very shallow, the recommended is f16 for 1:1macro. It will get worst at higher magnification the lens may even block off the lights. Best Get a flash and find a way to diffuser the light properly. Set the ISO at around 200 to 400 so that you get some ambient light too.Originally Posted by Xie Zhichun
May I understand more on diffuser? If someone can explain to me thanks
Just go and join a macro outingOriginally Posted by Xie Zhichun
Diffusing the light is one thing. Controlling your flash output is another.
