Levelling photographs using Photoshops ruler tool
This is a very quick and effective way to level up any photographs. It is particularly useful if you have photos of landscapes, and the horizon angle is incorrect. At a push, it may take 15 seconds per image - substantially less time then selecting the image, and rotating it around manually to the correct angle (that you would need to calculate..).
Keep a copy of the original image layer
As always, keep a copy of the original (tilted) image. Simply load the tilted image into Photoshop, and select the Ruler (measure) tool. This is an option available from the eyedropper icon on the tools bar.
Choose a reference line on your image to level
With the Ruler tool selected, decide which line you are going to level. In our example, we are choosing the horizon.
In images without a clear horizon, it will be necessary to choose some other line for reference - lines of pavements, roofs, skylines etc.
When the line has been chosen, simply draw it onto the horizon (keep left mouse down).
Once this has been done, simply select Image > Rotate Canvas > Arbitrary.
You will notice that Photoshop has prefilled the angle of rotation. After OK\'ing this, you will be left with a levelled image. However, this image will have some extra edges you may wish to remove.
Cleaning up the image using the crop tool
Removing these edges can be simply achieved with the crop tool. The crop tool is found, again, on the Tools bar.
With the crop tool selected, it is then possible to draw a rectangle marking out the area of the image you wish to keep. It is not necessary to be pixel perfect when drawing out the crop area - it wont cut anything away just yet, and the crop area can be adjusted by moving the "pull" boxes on the crop rectangle.
When the area to keep is completely marked out, simply press enter - or select the marquee tool on the Tools bar.

Checking for a sitemap A site map (or sitemap) is a list of pages of a web site accessible to crawlers or users. It can be either a document in any form used as a planning tool for web design, or a web page that lists the pages on a web site, Some developers feel that site index is a more appropriately used term to relay page function, web visitors are used to seeing each term and generally associate both as one and the same. However, a site index is often an A-Z index that provides access to content, while a site map provides a general... Read More »Center a web page in CSS
One simple way to center a web page using CSS is to create a container div, that is horizontally centered by having its left and right margins set to auto. Using this method, you can still apply colours / background images to the body tag, so its a flexible solution. (if you didnt need this ability, just apply margins and width to the body tag instead, and forget using the container div). The container div has the same width as your webpage and, well, contains it. All the code for your web page is placed inside the container div. This will... Read More »
