  2. Lightroom export resolution size for PTE Studio

    in General Discussion

    Posted

    Lin, Adobe has to take blame for the  "export" or "save to" 72 (or other) dpi/ppi misconception.  As we both agree it has no meaning when the output is to a display/projector.   Moreover the file size does not change regardless of what might be entered.   File size is determined solely by resolution and if file compression has been used.   I have proved this several times in demonstrations to my camera club. 

    I cannot condone using "Save for web" for club viewing or even home viewing.  Yes it reduces file size but jpg compression reduces viewing quality.

    A plea!

    If you are making a show with larger images and intend entering competitions, please remember that these large shows will take much longer to upload and download. 

    Also the poor competition secretary will have many to process and if everyone sends big files, they need a lot more storage space.

    Individual image files do not have to be big for projection. Even on a big screen you still only need 72dpi. Most competitions run on 1920x1080 or 1600x1200 projectors. Some smaller clubs are still using 1024x768

    So please resize your images if entering competitions or festivals.

    Thanks, Jill

    Hi Jill,

    I assume that your reply was directed to me and I fully recognise the need for moderation of file size.   Your comment about "only needing 72dpi" is however an example of a long since perpetuated myth.   Projector lcds,  computer screens and TV screens all have their own fixed ppi (dpi is a printer term).  No software can adjust the ppi of a projected or screen image.

    All of my images are either NEF or RAF raw files.  I use Adobe Lightroom Classic. 

    My NEF raw files are 7360x4912 pixels (3:2) and my RAF raw files are 4,288 x 2,848 (3:2)   I have no desire to shoot 16x9.

    As a PTE AV Studio newbie,  I would like advice regarding optimum file resolution when exporting from Lightroom.   

    (1) How does PTE handle a NEF to JPG export if I leave it at 7360x4912?

    (2) What is the minimum export resolution if I wanted to include zoom and pan effects?
