  • If the % scale is that much better, why does LR switch to the 0-255 scale with soft proofing?  I have given you reasons for preferring the 0-255 scale (which could also be presented as a hex value ...
  • But, whatever processing is used, the raw data is stored in binary meaning that powers of 2 represent the data better than powers of 10. Yes, but....  Suppose that I want to change a specific shade ...
  • Sorry, but I'm getting a bit frustrated now.  I have clearly said that I don't think that the added precision from using the % format has any value or meaning.  It is a false sense of precision.  ...
  • I wrote these response out of sync since I had an Internet failure for about an hour. I won't pursue this further after this post. You clearly know far more about color management than I do. I ...
  • I'm not disagreeing with any of this.  I was trying to point that writing extra digits to the right of decimal point do not generate more granularity or precision in the image.  That is fixed by ...
  • As I said in my previous post, the raw digital data is in binary.  For 8 bit files, that gives a range from 0-255.  For a 16 bit file, the range is from 0-65535.  If you use numbers on those ...
  • Maybe I'm having a bad day, but I don't see how this relates to what I was talking about.  I didn't say anything about LR changing the original file (I know that it doesn't change it).  I was ...
  • Interesting - I meant my comments the other way around for RGB.  The 0-255 is the more natural scale for reporting color because it relates directly to the underlying numerical data in the digital ...
  • Does it do a better job than Photoshop? Trying to decide what, if anything, MacPhun adds to a combination of LR and PS.
  • In one way, it doesn't matter (km/miles, F/C litres/quarts are all essentially the same).  But, in another way, it does matter. 0-255 leads to integer values for the color values because the ...
  • Thanks.  Excellent comments and advice. Does the fact that you have to convert your raw photos to tiff/psd/jpeg cause any issues for you?  Tiif/psd are much larger than raw files (several times ...
  • Replied in TrainSimple?
    Any experience or opinions about the TrainSimple videos?  They focus on Adobe products, with some general web design.
  • What he says :)  I never noticed that option.  Mine is set as active (show a 'hide' option) so I've never needed to use it.
  • Do you mean when viewing a directory in Finder using the icon view?  If so, I have Yosemite and there is a slider at the bottom right of the finder window which enlarges the small icon display of ...
  • I'm sorry - maybe I'm having a Friday morning moment. The OP posted a comparison of photos taken by the same lens, with and without the TC with the non-TC photo enlarged to the same field of view ...
  • Not sure that I follow why you would want to do that.  If I understand correctly, this would involve making the TC photo smaller.  Rather than doing that, if you wanted the smaller image, why ...
  • Maybe a dumb question but, could you clarify whether the tc image is on the right or left side of the photo pair :-)
  • I may have over-stated it a bit.  I didn't mean that you don't need telephoto reach.  I meant that you don't always need that reach.  Elephants are large :) and do get close to vehicles.  Our ...
  • Replied in MAC 27
    I'm in a somewhat similar position - a 2011 vintage 27" imac that I'm considering replacing.  I've read through a few similar threads recently. Here's one (just click) but there are others. The ...
  • If you search the site, there are lots of threads about photography equipment for safaris (e.g. Thread #1 and Thread #2) . Part of your answer might depend on whether you are planning to use any of ...
