10 Useful Greasemonkey Flickr Scripts

This post on Useful Flickr Userscripts has been submitted by Martin Gommel. You can see his work at his is a Flickr account and his blog KWERFELDEIN.

Userscripts are add-ons for the Firefox web browser, which dynamically enhance the communication and visualization of certain websites.

To be able to use these scripts you need to have installed greasemonkey on Firefox - this enables and manages the userscripts. If you have greasemonkey in Firefox you can install and use these userscripts instantly.

Following are the 10 most useful scripts for Flickr given in no particular order of importance:

1. Flickr Auto Page

This is definitely one of the most useful scripts for flickr. It allows you to scroll though a stream without clicking the “next page” - button. Older images are loaded automatically.

2. Flickr New Contact More Links

This script displays more useful information in you flickr-inbox about the user when they add you as a new contact.

3. Flickr Multi Group Sender

This one gives you the ability to post an image to multiple Flickr groups at the one time. Warning : If an image is posted in too many groups you reduce the probability of your image being explored ! I recommend adding images to a maximum of 5 groups.

4. Flickr Move Comment Form Up

This makes commenting on images a lot easier. This script always displays the comment box underneath you selected image - regardless of how many other comments have already been written.

5. Flickr Photo Rank

Photo Rank will show you a photo’s rank if it is in the top 1000 most interesting images of the day. After installation you can find it under “Additional Information” on the photo’s page.

6. FlickrPM

FlickrPM allows you to get important information about another user in a short amount of time by blending in different buttons next to the username on their stream (like icons for mail, profile, favorites, Scout and interestingness). Useful: With FlickrPM you can send the user a flickrmail without leaving the selected page.

7. Buddy Icon Reply

This i another of of my biggest time saver scripts for flickr. With it you will never have to copy&paste user names you want to reply to on your or other images. With one click you will get a little icon of the user you want to answer in your comment box. Nice !

8. Flickr Background Color

This script is all about aesthetics and is an easy to use tool that changes the background color on a photo page. It displays several shades of gray through to black. So if an image has a “dark feeling” the white standard flickr background won’t disturb it.

9. Flickr Follow Comments

This useful script helps you to view images that you have commented on - but only those that interest you. If you are writing lots of comments every day you know how hard it is not to get distracted by the overload of images when you click “Comments You’ve made”. With this userscript you have 4 different options to see only certain types of comments.

10. FlickrMailManager

This MailManager is the one of those scripts I will always value, because it makes handling your flickr-inbox much easier. For instance you can “mark all as read”, “delete group invites” and “nuke mailbox”. The processing time depends on the size of your inbox - so I use it very often.

DSC04296: Light Set 2.7

DSC04296: Light Set 2.7, originally uploaded by RMStringer.

I was outside shooting at some lights that we decorated a tree with. We placed green lights on the tree as you can see and we placed red on a tree that is about 15 feet behind it. So i focused on the green lights and let the red ones go out of focus. I guess that you could call this a "Night Macro" as i was about 4 feet away from the green lights and the 300mm focal length is in the Macro range of my lens.

Exposure: 0.1 sec (1/10)
Aperture: f/5.6

All were taken from my bedroom looking through the window with a screen on it. I love the out of focus lights and their reflections on the window. I was shooting through a screen on the window as well.

Exposure: 0.4 sec (2/5)

Depth of Field Calculator

Found on the DOFMaster Website

Depth of Field Calculator

Camera, film format, or circle of confusion

Focal length (mm)
Selected f-stop
Subject distance

Subject distance	10 ft

Depth of field
Near limit	7.6 ft
Far limit	14.6 ft
Total	7.04 ft

In front of subject	2.4 ft (34%)
Behind subject	4.63 ft (66%)

Hyperfocal distance	31.2 ft
Circle of confusion	0.02 mm

Use the actual focal length of the lens for depth of field calculations. The calculator will automatically adjust for any "focal length multiplier" or "field of view crop" for the selected camera.

Focal lengths of digital camera lenses are listed here.

Focus at the subject distance, 10 ft

	7.04 ft
7.6 ft		14.6 ft

	Focus at the hyperfocal distance, 31.2 ft

	Depth of field extends from 15.6 ft to infinity

Depth of Field Definition

Hyperfocal, near, and far distances are calculated using these equations.

Circles of confusion for digital cameras are listed here.

Depth of Field: The zone, or range of distances, within a scene that will record as sharp ... It is one of the most creative and profound effects available to photographers.

Using Your Digital Camera, George Schaub, 2003

Image clarity or sharpness is not just a matter of focusing a lens on the subject. There is an area in front of and behind the sharp focus plane that is also sharp or clear, and the extent of this area changes, depending on the focal length of the lens, the focusing distance, and the aperture used. This three-dimensional area of sharp focus is called depth of field.

Lonely Planet Landscape Photography: A Guide to Taking Better Pictures, Peter Eastway, 2005.

Hyperfocal Distance Definition

... the hyperfocal distance setting ... is simply a fancy term that means the distance setting at any aperture that produces the greatest depth of field.

How to Use Your Camera, New York Institute of Photography, 2000.

When the lens is focused on the hyperfocal distance, the depth of field extends from half the hyperfocal distance to infinity.

Photography, Phil Davis, 1972.
