Question

LrC - Image 'Resetting' after heavy masking...

Good morning all,

 

I am editing an image and using masks. One of the masks is heavily edited with lots of subtractions. I still have more subtractions to do but, all of a sudden, any further subtraction results in the pause while the programme thinks it over and then it 'resets' the image back to zero - i.e. no base adjustments and no masks at all. The history doesn't reset though - so if I 'undo' one step it reverts back to the state with masks, but the same thing happens again when I try to subtract again.

 

Any advice greatly appreciated.

 

Many thanks.

 

Paul

    What device - mouse, tablet etc - are you using to make these brush strokes?

     

    And have enabled automatic saving to xmp? Also, what is the file type?

     

    For that window, have you tried using the Object selection method, possibly with intersect if you're trying to select the glass or the frame?

    Hi John,

    Apple MacBook Pro i5. 

    File type is tiff (but the other image I originally posted about was dng). You are correct - I was trying to just select the frame. What I had done was 'add a mask' using a general brush that covered the whole window - I then used the 'erase' option of that brush to try and remove the excess (i.e. the walls and windows).

    I'm afraid I do not seem to have enable automatic saving to xmp - from what I can tell all metadata is stored within the dng(?).

    Many thanks and I look forward to hearing from you.

    Kind regards,

    Paul

    As a heads up on selecting the whole frame: use the Luminance Range and leave it full. You may need to move to range sliders to trigger the mask, but leave them at 0/0 and 100/100. 

     

    You can definitely use combinations of smart masking to reduce the number of brushes use, but if it's really intense and a TIFF as mention, you may be better using Photoshop with layered masks.

    About how many brushes (Adds, subtracts, etc) in that one mask?

     

    Their is a practical limit that most edits will not get close to. Are we talking dozens or hundreds?

    Hi GoldingD,

     

    Thanks for your reply. The answer is - quite a lot, probably 100+.  

     

    So, I guess I may have simply overstretched what is possible. Tomorrow I will try and edit again from scratch (couldn't face it today) and try and be more savvy. I will let you know.

     

    Many thanks.

     

    Kind regards,

     

    Paul

    You might want to share some screenshots, or perhaps a video capture of what you are attempting. Some members may have advice on a masking approach to work around your issue. Often when a very complex mask is in use, a different approach may be called for.

     

    Also other members may have advanced masking advise/tips, in the use of Add/SUB in Intersects, in brush selections

     

    Some members may request sample images via DropBox or other cloud share as to test.
