Hmm, that is not so. The preview is displaying the input. What you see is what you get. Please explain what size you are inputting and why you feel you are seeing a lower resolution. Maybe a link to the published tour?

This doesn't make a lot of sense I'm afraid.

300dpi information is "just a number" (you can type anything in there).

Where people get confused is with pixels vs dots. Dots are shown on a computer monitor and have "nothing" to do with printing. Printing information is PPI (pixels per inch)

What makes it more confusing is that people and software developers say DPI when they actually mean PPI.

The thing that confuses people is the "resampling" that is done to meet a DPI or PPI target. Test this in Photoshop with "Resample Image" turned off. You can change the number without the image changing size (or the pixel count).

If your image in size is 5000 pixels it makes no difference if the DPI information is 300dpi or 72dpi or any other number. It is still 5000 pixels and that's what counts. Print it and you are telling the printer to print it with 72ppi or 300ppi. Obviously, 300ppi will be better with more pixels printed in every inch. Display it on a computer monitor you cannot see any difference between 96dpi and 300dpi the image remains the same 5000 pixel count image.

If you have an image that is 5000 pixels and 300dpi as the input and after you convert the image to .jpg it is now 5000 pixels and 72dpi the fact is the image is still the same based on the dpi alone (only the printer instructions have changed).

Clear as mud.

Now, DPI and PPI aside.

You are modifying the image when you convert from one format to another and this is done via interpolation. Different interpolators effect images in different ways.

Anytime you are going to manipulate an image (photograph) you should keep your workflow in a non lossy format. I prefer .tif and more than that I prefer 16 bit .tif files.

At the end the image will always be displayed as a .jpg (or .jpg cubes) but this should always be the very final conversion and there are most certainly best practice ways to get the final .jpg result from your near perfect 16bit .tif files.
