Resolution issue

[davidheim1]

I'm new to this forum, so please exuse me if I'm asking a question that has already been dealt with.
Here's my problem:
I inserted a SketchUp file into LayOut, then exported it as a JPG at 300 dpi. However, when I open the exported JPG file with Photoshop, it opens at 72 dpi. Same thing happens if I try exporting the file as a .png at 300 dpi. It also happens if I export the SketchUIp model directly as a TIFF at 300 dpi.
Anyone know why the resolution changes between the LayOut export and Photoshop?
Anyone know how to keep the resolution from changing like this?

Many thanks,
David Heim

At a guess PS might have opened it at 72 DPI but also increased the pixel size to account for this.
DPI is only really relevant when matched to a set size (8.5"x11", for example).

If you had a 1920x1080 image exported then at 300 DPI it would make a 6.4"x3.6" image. If PS shows it as 72 DPI then it would be a 26.6"x15" image.

In PS you can then adjust the DPI and the size of the image will adjust accordingly. It's the number of pixels in an image that matter -- not the DPI.

Most helpful. Many thanks.

Compare the overall pixel count (width & height) both in the jpg and in PS.
