Do not let image manipulation software replace good science.Enlarging an image with a small number of pixels can lead to artifacts (see guideline 12).This means that if an image is to be 3.5 inches wide in the journal, it needs to have 1050 pixels. Most journals require a minimum of 300 dots per inch (DPI) for images. ScreenPals free image cropper is a simple yet powerful tool that allows you to crop your images to any size or aspect ratio. Cropping out gel bands that might disagree with the hypothesis being proposed in the paper.Cropping out dead or dying cells, leaving only a healthy looking cell.Click the 'Crop Image' button to crop your image.

The act of selecting a specific area on a sample and the magnification at which to capture the image is a form of cropping. Acquiring scientific images requires us to consider what is important in the sample.The reality may be that it was a small group that was crowded together to make it appear in the photo as if there were more people present. Example: A tightly cropped image of a political protest can give the impression that there was a large crowd at the event.This can be very useful in art photography, but the same technique used in news or scientific photography has the potential to be misleading.

Next, click-and-hold the Eraser Tool icon in the toolbox (highlighted red below) and release the mouse when hovering over the Crop Image Tool.Cropping can be used to make an image smaller (in pixels) and/or to change the aspect ration (length to width) of the image.
