Lightroom Resizing Photos Problem

What is the resolution of your display (in pixels)?

If you have a Retina display, web browsers will scale everything, including images to 200%.

This is to compensate for the small pixel size, and to ensure that everything is displayed at a "normal" size.

I don't use a Mac, but suspect that native apps, like Mac Preview, do the same thing.

There are methods to get around this problem in web browsers, which include uploading two versions of the image to the website. The second version will typically have double pixel dimensions, and the file name will be appended with @2x - like image@2x.jpg.

The website will need to be coded to enable the @2x images to be used, and the result is that the browser will display the @2x image without scaling it on Retina displays, while the regular image will be displayed on regular, non-Retina screens.

richardplondon wrote For example: say a system was designed to deduce a supposed printing size for each image, and then to generate a screen viewing version to a standard resolution based on that supposed printing size. One can imagine two versions of the same image being input to such a system, varying only in their PPI: image 1000x500px @ 300ppi; interpreted as 3.33 inches wide; this resampled @ 72ppi = 240px wide preview image image 1000x500px @ 72ppi; interpreted as 13.89 inches wide; this resampled @ 72ppi = 1000px wide preview image.]

This is more or less how Indesign works, since it is used for creating printed documents, it uses the ppi to preview the printed size of an image. But web browsers don't care about ppi, they display images according to their pixel dimensions.

Here are the screen captures of the the same image they are both JPEGs and exported in Lightroom the only difference is the sizing. Which is what I need to export them at for my works website and to also clear up some confusion when another co-worker exports his photos under the same settings they are nowhere near as soft as mine. Also if you take one of my photos off the website and put it into photoshop it becomes much clearer. The top pic is soft and the bottom pic is clear using preview.

No importing the original RAW files into lightroom and then resizing them in lightroom and then exporting them in JPEG format resized to the 1000pix.

When they look soft, what magnification are you using to view the photos? What software are you using to view the photos? Show us a screen capture of the not-soft photo as seen in Lightroom, and another screen capture of the soft photo as seen outside of Lightroom 

Do you mean that you are exporting them as JPEG's first, and then resizing them? Why not export from the raw files and resize them in one single operation if that's not what you're doing?
