Hello everybody. I have a question.
I need to publish some photos in a scientific article, the magazine requires that the photos have 300 dpi, but my camera took the photos at 72 dpi. I have seen that the change can be done in photoshop, but the images are smaller. Has anyone experience changing dpi in a software for a scientific publication? and have accepted your photographs?
Thanks for your help.

Uncheck the "resample image" checkbox when rescaling in photoshop or similar programs. layersmagazine.com/photoshop-resizing-images.html. There is 3 values at play, dpi (dots per inch), number of pixels, and physical size of an image. In the end you might want to keep pixels the same, have a higher dpi value, but the physical size of the picture will change.

if the photos wer originally at 72 dpi, the only way to obtain at 300 is to reduce them (it is mathematical) otherwise you will obtain softwared 300 dpi photo but in 72 dpi resolution and picture will probably be pixellised. You can attenue the pixellisation but you will will never obtain a real 300 dpi ressolution.
You can miwx the two. redusce the picture at the required format (depending on the revue/ editor) and after make a software 300 dpi relsution. The way I had used in your case.
