    Urbane got a reaction from FlixelPix in Fuji X100v Image Quality   
    Thank you Herco for taking the time to reply, much appreciated.  Prior to my post, I chose the aspect ratio 3:2, image size Raw, and uncompressed and these were the settings used for the dimensions in the post.  I haven't looked at jpeg yet but think that can wait.  As you suggest, I will use uncompressed for real world use.  Perhaps the problem is not being familiar with camera yet and probably the reason for the softness.
    What still puzzles me is the DPI setting.  With the Olympus file, I determine the physical print size (usually 33cms x 24.75cms) in a 4:3 aspect ratio which is not much different to out-of-camera size and then reduce the DPI to 300 (approximately 15%) which is normal for printing.  The Fuji out-of-camera file by comparison is much larger as understood from your reply but for printing purposes, I would have to increase the DPI from 72 to 300, an increase of over 400% with the software resampling many, many pixels.  I hope I have made my issue clearer.  
    Regards

    Hi Urbane, 
    A photo shot at 6246px x 4170 pixels is the same whether or not it is saved with a 72dpi or 300dpi. 
    You can change the dpi without resampling by unclicking the Resample check box and entering the desired dpi.  This will have no effect on the file resolution - just the output.
    Example:  For the Fuji 6246px x 4170px file at 72 dots per inch  (read pixels per inch)
    -  6246px / (72 px/inch) = 86.75 inches  = 220.25 cm
    - 4170px / (72 px/inch) =57.52 inches = 147.11 cm
    If you change the dpi to 300, uncheck the Resample box the image resolution of 6246 x 4170 px will not change, only the size of the output.
    -  6246px / (300 px/inch) = 20.82 inches  = 52.88 cm
    - 4170px / (300 px/inch) =13.9 inches = 35.31 cm
    Now, let's say you save the above image at 300dpi and send that image to a printer to print a 12in x 8in print at 300dpi, then the printer will use an internal algorithm to down sample from 20.82in x 13.9in to 12in x 8in. 
    OR
    You can take control of the down sample method by changing the resolution of the image in Affinity Pro (or whatever software you use) using the dialogue box in your previous post and changing the size of the image to 12in x 8in,  changing dpi to 300,  clicking the resample box and selecting the resample method / algorithm then saving the image.
    Often, after resampling, you may find you have to sharpen the image slightly to get the best printed output - especially if you are upsampling.  Taking control of the process enables you to do this rather then relying on the printer.
