    I am new to photography, and I dont understand what "tonal range" means". In that particulay editor choice awarded photo, could you possibly tell me what is the tonal range ?
    I want to understand, so I can get better.
    Thank you for your help.

    just think of a full gradient from pure white to full black as being a full tonal range.

    sometimes the tonal range displayed in an image is just dull grey to black this is a limited tonal range.

    if you have well balanced mono conversion from white to black you will have a full range of tones.

    sometimes you will have a high contrast image which is white to black with very little grey tones.

    its generally understood that a good mono print will contain a full range of tones. although this is not always the case or possible due to the lighting conditions.

    when processing, check the histograph and look at the curve of the graph, if the spread of the graph is a nice curve reaching right up to the pointers each end you will be all right, if its all bunched up at one end you will not have a full range of tone.

    there are many ways of doing the conversion but using the channel mixer is the most reliable.

    That image does have a tonal range yes, but in my view I would call it a limited tonal range.
    All images have a tonal range, but you can go on forever with descriptions for them, muted tonal range, limited, compressed, etc etc.
