    The only general rules are to keep an eye on the histogram while making changes so that the adjustment does not cause any color to move beyond the edges. Reduction in exposure could make some colors to fall off the left edge causing details to be lost into blackness. Similarly, Increasing the exposure may make the colors to exceed the right edge resulting in bright patches.

    Hi Hardik, those are valid ways of using the camera. In either case, it should be possible to use back-button focusing. AE Lock allows exposure to be locked for recomposition and can be used with back-button AF.

    It is most useful when there are many elements in the foreground and you want to achieve focus on a specific subject. More than anything, Back-button focus forces you to separate the focusing and shooting functions so that you will consciously produce pictures with focus on the subject that yo want to be in focus.

    I check the histogram when the lighting conditions are difficult.

    Lightroom actually shows three histograms in one window, each histogram representing the primary colors Red, Green, and Blue. The secondary colors Cyan, Magenta, and Yellow appear wherever the histogram areas of primary colors are overlaid on one another. The place where all the three primary colors are present is shown as Gray. You can individually figure out whether your adjustments, say saturation adjustment, is going to push any of the colors beyond the edge.

    Thanks for reading.

    Thanks Prema for reading.

    To your first question – Can one zoom in and out once focus is locked? You can zoom in and out, but the question is whether the subject will still be in focus. Depends on the lens. As per specifications most of Canon L series lenses are supposed to. But I will never trust that. If I zoom in or out, I will focus again.

    Do you also change to Spot Metering? First spot metering should be used with care. Unless I have a reason to use Spot Metering, like back-lit subjects, I will not use spot metering. Since we will be recomposing after acquiring focus, there is no point in metering just on that point. The answer is NO.

    Looks like a good thread to discuss more on these distinctions.
