I only recently learned about bracketing, which means I now know more about bracketing than I know about PP.
I was talking more about camera settings. And I don't mean f/11, 1/200, ISO 800. I mean things like spot metering vs evaluative metering, camera settings like the "highlight tonal priority" setting, which I found out about this morning.
In general, evaluative metering is best for most landscape shooting, but my advice would be to shoot raw and use the histogram to gauge how well you've exposed the scene. Getting accurate histograms requires using settings that make the photos look a bit bland on the LCD, but it's a worthwhile compromise. (The very best way to get accurate histograms is to use UniWB, but that's an advanced technique that is the subject of long threads here.)
Try this test to get reasonably accurate histograms:
Step One: I recommend starting out with "Picture Style" set to "Neutral" and with anything else that might affect the JPEG preview turned off. Leave the settings for Highlight Tone Priority and Auto Lighting Optimizer turned off. Turn on the option to have the Highlight Alert (a.k.a. "blinkies") display when previewing photos; it will indicate any areas where you have clipped highlights. Then go out and take some test photos, trying to expose so that you have histograms that lean as far to the right as possible without clipping any highlights. Use the option to see all of the histograms (RGB and Brightness); make sure that none of them have data clipped on the right side. You should see no blinkies in your preview.
Step Two: Now open these files in a raw editor and make sure that the histogram is visible. Confirm that what you were seeing on your camera's LCD is accurate. You should have no clipping at the right but also very little headroom remaining (i.e. you're as close as you can get to the right without clipping). If your data at this point looks pretty close to what you were seeing on your camera's histograms, then you're all set. If it's not very close, then try adjusting the "Picture Style" settings until your camera's histograms are more accurate (the Sharpness setting in particular can have a big effect on the histogram). The worst case scenario would be to have a histogram that reports the data as being darker than it really is (i.e. it's skewed too far to the left, telling you that there is no clipping when there actually is clipping in the raw data). If it's reporting clipping a bit too soon, that's not so bad; then you can shoot knowing that you have a bit of headroom beyond what the camera is reporting.
Once you've gotten your settings on the camera to where they produce reasonably accurate histograms, then it really doesn't matter what metering mode you use. Check your histograms habitually while shooting and expose as far to the right as possible without clipping any highlights (anything that is clipped is gone forever, and since the eye is attracted most to the brightest areas of an image, those are the parts that you most want to protect).
I just read a thread (and the links contained within) about GND filters and plan on getting some. A lot of light bulbs went off for me while I was reading that thread. Thanks, Phrasikleia (I hope I am pronouncing that correctly, ha!)
In the last year I have gone from not knowing what would happen if I changed the aperture (hell, I had to concentrate to remember that a higher number meant a smaller opening!) to having a firm grasp on f stop, shutter speed, and ISO. So I am learning, but I still have a long way to go. I kind of feel like I should learn to take good pictures first, and then learn to maximize them in PP afterward.
Yes, definitely work on mastering the camera first. I personally do not use GND filters anymore, but they are great for anyone who has not yet learned post processing or simply does not care to do much of it. That said, I would recommend that for your most exciting situations you do some bracketing without the GND filters for future use. Get the shot with the filter, but also try to get a bracketed set in case you later learn some advanced processing techniques and want to revisit some of your best shots.
Hope this info helps. Enjoy!
