Deauthorising Adobe Digital Editions software

My being partial to the occasional eBook has meant my encountering Adobe’s Digital Editions. While I wonder why the functionality cannot be be included in the already quite bulky Adobe Reader, it does exist and some publishers used it to ensure that their books are not as easily pirated. In my case, it is a certain publisher of walking guidebooks that uses it and I must admit to being a sometime fan of their wares. At first, I was left wondering how they thought that Digital Editions was the delivery means that would ensure that they do not lose out from sharing of copies of eBooks but a recent episode has me seeing what they see.

One of the nice things that it allows is the sharing of eBooks between different computers using your Adobe account. Due to my own disorganisation, I admit to having more than one though I am not entirely sure why I ended up doing that. The result was that I ended entering the wrong credentials intro the Digital Editions instance on my Toshiba laptop and I needed to get rid of them in order to enter the correct ones. It is when you try doing things like this that you come to realise how basic and slimmed down this software is. After a Google search, I encountered the very keyboard shortcut about which even the help didn’t seem to want to tell me: Control+Shift+D. That did the required deauthorisation for me to be able to read eBooks bought and downloaded onto another computer. Maybe Digital Editions does its job to lessen the chances after all. Of course, I cannot see the system being perfect or unbreakable but a lot of our security is there to deter the opportunists rather than the more determined.

O’Reilly does eBooks…

I have been a Safari subscriber for a while now and access to O’Reilly titles has been the main reason behind it. However, I recently discovered that O’Reilly is offering full eBooks of some of its titles. Why the offering is far from complete, this is progress and the prospect of donloading complete books with proper page numbering and an index is an appealing. Previously, I was downloading the individual chapters from Safari and compiling the books in that way, a less than user friendly approach. So, do I continue the Safari subscription or not?

SAS books now on Safari

Being a Safari subscriber, I found a pleasant surprise awaiting me in this month’s email newsletter: eBooks from SAS Publishing are now available on Safari. Having a quick look, I found a small but useful selection. Topics like the SQL procedure, the Macro language and Enterprise Guide caught my eye but there’s more than this on offer. It’ll be interesting to see where this leads…

The joys of eBooks

One of the nice things about eBooks is the saving that you can make on buying one instead of the dead tree edition. And if you get one from Apress, it is the full article that you get and they keep it available so that you can download another version if you need it. You can also print the thing off if you want too but a laser printer producing double-sided prints is an asset if you don’t want your space invaded by a hoard of lever arch binders. Having a copious supply of inexpensive toner helps too as does cheap paper. Otherwise, you could spend your savings on printing the thing yourself.

The ever pervasive Safari does things a little differently from the likes of Apress. Mind you, the emphasis there is on the library aspect of the operation and not eBook selling. The result is that you can only ever download chapters, so no index or overall table of contents. You still can buy all of the chapters for a particular book, though some publishers don’t seem to allow this for some reason, but finding anything in there after you have had a read becomes an issue, especially when it’s the hard copy that you are using. Take yesterday, for instance, when trying to relocate the formatting parameters for the UNIX date function. I eventually found them in the chapters of UNIX in a Nutshell that I have downloaded and printed off but I spent rather longer looking in Learning the Korn Shell than I should have done. I know that you can search in the PDF’s themselves but that is more laborious when there is a number of files to search rather than just the one. I suppose that the likes of O’Reilly prefers you to buy paper copies of its books for more extensive use, and they have a point, but having the electronic version all in one file does make life so much easier.

Photoshop CS2 workout

I am in the process of adding new photos to my online photo gallery at the moment and the exercise is giving my Photoshop CS2 trial version a good amount of use. And the experience also adding a few strings to my bow in graphics editing terms, something that is being helped along by the useful volume that is The Focal Easy Guide to Photoshop CS2.

The biggest change that has happened is that to my workflow. Previously, it took the following form:

  • Acquire image from scanner/camera
  • For a camera image, do some exposure compensation
  • Create copy of image in software’s own native file format (PSPIMAGE/PSP for Paint Shop Pro and PSD/PSB for Photoshop)
  • Clean up image with clone stamp tool: removes scanner artifacts or sensor dust from camera images; I really must get my EOS 10D cleaned (the forecast for the coming weekend is hardly brilliant to I might try sending it away).
  • Save new version of image following cleanup.
  • Reduce size of digital camera image to 600×400 and create new file.
  • Boost colours of original image with hue/saturation/lightness control; save new version of file.
  • Sharpen image and save another version.
  • For web images, save a new file with a descriptive name
  • Create JPEG version
  • Copy JPEG to Apache web server folders
  • Create thumbnail from original JPEG

The new workflow is based upon this:

  • Acquire image from scanner/camera
  • For a camera image, do some exposure compensation; there is a lot of pre-processing that you can do in Camera Raw
  • Create copy of image in software’s own native file format
  • Clean up image with clone stamp tool and create new file with _cleaned as its filename suffix. I tried the spot healing brush but didn’t seem to have that much success with it. Maybe I need to try again…
  • Add adjustment layer for level correction and save file with _level suffix in its name.
  • Add adjustment layer for curves correction
  • Add adjustment layer for boosting colours with hue/saturation/lightness control
  • Flatten layers and save new image with _flatten suffix in its name
  • Sharpen flattened image and create new version with _sharpened suffix in its name
  • For web images, save a new file with a descriptive name
  • Create JPEG versions in Apache web server folders; carry out any resizing using bi-cubic sharpening at this point.

There remain a few things that I could do to improve on this. For instance, separation of raw, intermediate and final photos by storing them in different directories is perhaps one possibility that I should consider. But there are other editing tricks that I have yet to use as well: merged and blended layers. Bi-cubic smoothing for expanding images is another possibility but it is one that requires a certain amount of caution. And I am sure that I will encounter others as I make my way through my reading.

Photoshop books

Having exhausted the trial time on PhotoShop Elements 5, I am now having a look at its big brother PhotoShop CS2. That has got me thinking about PhotoShop books so that I become more of the possibilities and how to use them. Having a Safari subscription as I do, that naturally became my first port of call and I seemed to find two that answered my needs. Both are by Scott Kelby and they now lie on my Safari bookshelf: The Photoshop Elements 5 Book for Digital Photographers and The Photoshop CS2 Book for Digital Photographers. Even so, I am tempted to get a dead tree version of one of them and that presents a chicken and egg dilemma: the books could help choose which software to buy and the software dictates which of them will be the more useful. That said, I suspect price and features will swing it the way of Elements 5; paying over £400 for software whose capabilities I may never need does not sound financially sensible.

Update March 5th, 2007: I have now got my mits on the dead tree edition of Scott Kelby’s The Photoshop Elements 5 Book for Digital Photographers as well as Brad Hinkel’s Focal Easy Guide to Photoshop CS2. Now for some reading…
