How to Limit the DOF I have recently upgraded to a Maxxum 5 from a Maxxum Stsi and was confused about the DOF preview function. I want to take some portraits or close-up shots where the background would be blurry but the object sharp - i.e., limit the depth of field. I understand that a larger aperture would achieve this, but when I look through the viewfinder with the DOF preview, the screen is bright ... and at smaller apertures, the viewfinder is dark. As a rule of thumb, to limit the DOF, the brighter the viewfinder, the better? And should I use the recommended shutter speed by the camera? Or is a faster shutter speed better?

Yes, generally speaking, the brighter the viewfinder when you use the DOF preview the more you'll limit the depth of field. The reason it's brighter is because the larger aperture lets in more light and the smaller the aperture the darker. To compensate for a larger aperture (more light) you need a faster shutter speed and vice versa for a smaller aperture. If your camera has an Aperture Priority mode, then when you tell the camera what size aperture you want it should make the appropriate adjustments to the shutter speed to give the right exposure.

Well I won't repeat myself but do see the previous question regarding Depth of Field and what it does and more to the point how to use it. Jordan brings in to your question that of exposure. Sometimes you want to overexpose sometimes you don't so simply using A mode isn't necessarily the thing to do .....IF you are trying to over/under expose for creative purposes. Learn to see through the darkness......just as your eyes adjust to walking into a dark room so will your eyes and your brain learn to see to what is going on when you
