Visible watermarks are good if you’re distributing images directly. Small watermarks can bely removed in Photoshop, so consider including diagonal lines which cover the full dimensions of the photo and make removal harder. A typical watermark is a PNG file with about 40% opacity. This can look very professional, and is the method of choice for many microstock companies. Big, bold letters covering most of the photo are almost impossible to completely remove in Photoshop.Īn attractive way to do this is to add, on top of the photo, a transparent image, called a watermark. The only way to ensure that your copyright info remains displayed with the image is to write it all over the image. Requires effort and degrades the displayed image. Most stock agencies and many photographers Other image-editing software, or an online service Online image resizer toolsĪdd transparent text or a logo on top of each photo. on web sites, provided that no Image is displayed at a resolution greater than 800 x 600 pixels.” “By this Agreement, Shutterstock grants you a personal, non-exclusive, non-transferable, right to use and reproduce Images. Shutterstock, for example, limits the size to 800 pixels. If you’re licensing your images directly, you can include a condition that the client not display the image online above a certain size. For your own website, you can resize your images in Photoshop with Image > Image Size. Many websites, such as Flickr, will automatically resize your images upon upload. And, if they do, it certainly won’t be on the cover or a full-page spread. So, if you keep your images to 640 pixels or less, it’s unlikely that someone will print your photo on a brochure, book or magazine. For example, a 640-pixel-wide photo show on a 100dpi computer display is 6.4 inches wide, but only 2.1 inches on a 300dpi print. Thus, when printed on a brochure or postcard, the photo’s size is reduced by about a third. Printing usually requires about three times the detail of computer display (for example, 300 dots-per-inch vs. It’s the standard width of an XGA monitor, and a large Flickr image. Why 1,024 pixels? That’s the typical maximum width of a website page. It’s the standard width of a VGA monitor, and a Flickr image. This article was updated in January 2021 by the editor.Why 640 pixels? That’s the typical width of a website’s main text column. If the height is fixed and the width proportionally variable, it's pretty much the same thing, you just need to switch things around a bit: blog and republished under Creative Commons with permission. You can use the same filename to overwrite the full-size image with the resized image, if that is what you want. Also, notice I saved the resized image under a different name, resized_image.jpg, because I wanted to preserve the full-size image ( fullsized_image.jpg) as well. You can change basewidth to any other number if you need a different width for your images. The resulting height value is saved in the variable hsize. The proportional height is calculated by determining what percentage 300 pixels is of the original width ( img.size) and then multiplying the original height ( img.size) by that percentage. These few lines of Python code resize an image ( fullsized_image.jpg) using Pillow to a width of 300 pixels, which is set in the variable basewidth and a height proportional to the new width. Img = img.resize((basewidth, hsize), Image.ANTIALIAS) Hsize = int((float(img.size) * float(wpercent))) Here's a basic script to resize an image using the Pillow module: from PIL import Image To install Pillow, use the pip module of Python: $ python3 -m pip install Pillow Scaling by width So I looked around and found Pillow, a Python imaging library and "friendly fork" of an old library just called PIL. Some time ago, I wrote a Python script where I needed to resize a bunch of images while at the same time keeping the aspect ratio (the proportions) intact. I love Python, and I've been learning it for a while now.
