Originally posted by sebberry On the fixed screen: I was trying to take some photos today of a heron from low to the water surface. Screen on maximum brightness and all I could see was a reflection of me and the pebbles around me on the beach. Had no clue where it was trying to focus and in typical Pentax AF fashion, it was more often selecting something other than the bird to focus on.
Low-level shots can certainly add interest to a subject, especially on the water surface.
I don't have much experience with my K-3 Mark III in this type of setting. However, there might be a couple of approaches you could try next time.
I think Live View is better when the camera is mounted on a tripod -- there's more control of its orientation, less movement of a large lens, and easier selection of focus points. I also think a static camera allows the user to concentrate better on the scene and subject -- all the advantages of using a tripod in general. Perhaps use a tripod in its lowest position. I have a regular tripod that can get the camera as low as about 10 inches; my small mini-tripod can drop the camera to half that. Of course, it's still necessary to crouch down or kneel to operate the camera. This assumes a fairly stationary subject such as your heron.
Not sure why the subject wasn't apparent with the rear screen at max brightness. Maybe the scene was relatively dark compared to your brighter clothing or the rocks. Increasing the exposure might help to brighten the subject in the display.
Sounds like the camera was set to Auto Area AF or another auto AF mode. It's possible that the AF would be more assured if Sel (S) is used and the desired focus point is tapped on the screen.
Finally, contrast detection AF is not perfect -- it may struggle in scenes with relatively low contrast.
