Nature Division Study Groups: Image Preparation Guidelines
For vertical images, make the height (the longer side) 600 px
Make any enhancement, including sizing, flipping or rotating, in a format other than JPG (e.g., PSD). Repeated editing and saving a JPG file can degrade image quality. This is also true if you rotate your image using software and not in the camera. Renaming a JPG file using your browser or opening a JPG file and closing it without any changes will not degrade the image quality. If you get the prompt "Save Changes Before Closing" when closing a JPG file, answer "NO."
Do not submit your original image. Use a copy. This will always leave you a master of the original image you made.
All images should be given a descriptive Nature title.
The filename for each image must use the following format:
where: Image_Name is the title of the image and Lastname is your family name
