Are you saving both jpg and raw in camera, and comparing those? Shoot raw then process in post and export as jpg.....or do you do post processing?.

Indeed. Since you can't print a RAW, or even view it for that matter, what are you using to convert and view the RAW vs the jpg?
I use Photoshop to go straight to editing because i have little free time and edit only photos i find interesting. I revert to the native brands software if its not possible to open the files directly with PS.
This fit me because I shoot RAW only if i'm getting paid.
For my own use, i have allocated one button on my camera to shoot Jpeg+RAW so i have an instant option if i want to because generally, i shoot with my own picture control settings directly to Jpeg.

My apologies for the delay in replying, I do appreciate the comments.
I only shoot in RAW and process in LR.
I think that I have found the issue after going through some of Anthony Morganti's tutorials.
Firstly my monitor was off wack as far as calibration and so I wasn't seeing what I thought I was seeing (or I was seeing what I thought I was seeing but I was seeing the wrong thing!). Secondly, in LR saving as an Export or printing to a File appears to be different. (I don't know anything about computers so please don't leap on me for that). If you Print to a JPEG file then you can 'correct' how the picture is saved, just as you would if you were printing and altering aspects of the printer and paper etc.
This is the same picture of a Tent-Orb Weaver saved as a 'Print to a File" as compared to the original - see above.
My apologies for my naive questions I only took up photography 12 months ago and it is a BIG learning curve!!!
Thank you again everyone.

The algorithms certainly will not purposely single out adjustments for sharpness. I would expect it would affect sharpness by the same ratio as the rest of the photo. The loss of data is the reason you choose low loss compression when you prepare a picture for printing. The loss of data is directly related to the amount of compression: the greater the amount of compression, the greater the loss. Most photo processing s/w uses a quality measure which inversely related to the compression, high quality means less compression.Are you suggesting that if I adjust the sharpening in - camera, that this could then be cancelled out by the data being discarded?

I find that JPEG need less work than raw, which always need processing, especially for sharpness.
My experience Jerry you are right on!!
