When object is far more than half hyperfocal distance (f5.6), you can get a deep DOF picture.

When using this method,you don't need the app usually. The app can give you a better understanding of the method. You can also use the app under special circumstances.

It's a good method to estimate hyperfocal distance. But it's hard to find the location of hyperfocal distance (distance scales of autofocus lenses is not enough fine), i.e., I know hyperfocal distance is 25ft or 50ft, but I don't know where to focusing. "standard height multiple of short side...

It should be that "If I want to capture (or snap) a man".

You master many rules and broke part of the rules. The composition guide is useful to amateurs and new photographers. For professional photographers, you can break any rules to create a better work.

F5.6 is hard to use in this case, if F5.6 can meet the situation, I will use F5.6. If I want to captured a man, tripod is useless.

You are out of context. I said "under a dim light of the scene".

I have said that we can mental calculate rather than using DOF calculator usually. Firstly, it can quick estimate the location of hyperfocal distance. For example, under a dim light of the scene, I take a full frame camera with 35mm lens. I want to take a deep DOF photo. If the aperture is set...

You don't have finished reading this method. So Your conclusion is too arbitrary. James is a new one. He should learn a wider range of knowledge. Photography technique is also important. You couldn't give him the wrong guide.

Superb photography technique can help the photographer to create better works. If you want to exchange photography art, please go to other relevant threads. Here we should talk about the photography technique rather than photography art. The bokeh rank method is a little hard to read. If you...

I think the decrease of sharpness is due to the lake of pixels (when enlarge it to a certain size) rather than the minimal difference of DOF, is it right?

Camera Calibration is one of the difference, it's color setting. sharpening and noise reduction is also different. DPP apply default aftereffects. You can adjust picture with your method.

Usually, we can mental calculate rather than using software, so it's very fast. If you have several lens and several cameras of different sensor size, it's hard to remember how to set the parameter, such as focus distance, aperture.

For auto focus lens, the distance scale is rough. It's hard to use depth-of-field scale to estimate DOF, because we don't know the focus distance. Here use reference height to fast estimate sharp and bokeh. It's completely mental calculate. Software...

Canon S95 is a good camera. If you regist Av mode to C mode, you can define the focus distance, aperture. This moment, if you define ISO auto settings as standard rate of change, the time of exposure is set to 1/60 priority. When you want to shot, you only need to open the power button and...
