Panoramas and a wet afternoon

clock Monday October 20 2008 17:05

I've struggled with how to display panoramas on the web, previously using just the browser to display them. The standard flash plugin I'm using doesn't render them well: it works best with images of consistent size. "Lightbox" gets around that issue. The original Lighbox is Prototype/ Scriptaculous based. I like those, but MS are moving towards JQuery, and as this is running on ASP.NET, I used the JQuery Lighbox extension.

I lashed up a little extension to BlogEngine.NET which squirts out the magic incantations required for JQuery and the Lightbox extension to it, and then I hacked someone's thumbnailing extension for BlogEngine.NET ... so now I can drop images in here and they're automagically thumbnailed and displayed in a lightbox.

Like this:


These are all huge panoramas, so you'll need a fairly large screen to see them. I do have a bunch of nodal-point gear, but these were all taken hand-held and then stitched using PTGui and/or Photoshop. And as they're displayed without browser plugins, they're pretty much the only photographs on this site which you can see in the correct colours.

I found the BlogEngine.NET extension handler rather flakey. The principle's great, but it needs a little polishing. Unless you happen to have a wet afternoon to spare.

Why it doesn't work the way most people think it does, and how to make it work the way it should work.

1 Introduction

If you're a photographer then colours are important, and you'll want to see the same colours coming from your monitor as you saw when you shot the picture. You also want to be sure that anyone else viewing your images sees what you intend them to see.

Photoshop CSx Save for Web

clock Tuesday December 27 2005 14:50
CS3

introduction

In Photoshop CS3, CS2 (and earlier versions) you can't automatically save an image to a specific size for web use. You can do this manually via "save for web", and the "optimize to file size" feature there, but you can't automate that in an action. The reason is that the "save for web" action which is recorded has a "quality" value specified, not a target size.

The scripts here provide this "save to target size" feature for CS2 and CS3.
