Many photographers use photoblogs to promote and market their work and services. Photoblogs can be great sources of information and inspiration for photographers, as well as for anyone who likes to look at beautiful images.  This post describes photoblogs and provides some examples. I’ll talk about how to create a photoblog in a future post.

Photoblogs are blogs that are made up primarily of photos. But photoblogs usually includes more than just pictures. (If pictures are the only content you want to publish, it would be easier to use an online photo hosting service like Zenfolio, Smugmug, or Flickr.)

The advantage of a photoblog is that it provides a historical or autobiographical dimension.  Text gives context to the  images. Often a photoblog resembles a journal or a documentary. Photoblogs are a good way to tell a story with your pictures.

Here are a few photoblogs I have looked at and benefited from. Some of these bloggers are quite well known; others aren’t.  Some of the blogs are oriented towards illustrating photography techniques; others are more personal explorations of art and ideas.

Image resolution and print size

The following screencast uses Photoshop, but whatever image editor you use, the concepts are the same:

(1) There is an inverse relationship between print size and resolution (if you increase the print size the resolution decreases and vice-versa).

(2) To get good results when inserting an image into a research poster, the image should be printed at a resolution of at least 200 pixels per inch (ppi).

(3) Images that look good online may not be high enough resolution to look good in print at the size you want them to be.  For example, an image of 640 by 480 pixels may look fine on your computer screen, but printed at 200 ppi it would only be 3.2 by 2.4 inches in size.

Resolution and print size for images

Here is a convenient reference table from

Resolution & Print Size chart

If you want very high quality you need to print at a resolution of at least 300 pixels per inch (ppi). (Of course, you need to start with a good original image.)

Generally, a resolution of 200 ppi is fine for images to be inserted into posters that will be presented at conferences. 300 ppi is even better, but not necessary.  A resolution of below 150 probably won’t look very good.

So, for example, if you want to insert a 10″ by 7″ photo into a poster, the image should preferably be at least 2000 by 1300 pixels to look good.
