One MUST fundamentally first understand that what LR does is NOT the same as what Adobe Creative Suite does. Consider that the range of functions to be found in various software consists of the following
1.RAW conversion (takes .CR2 files to JPG or TIFF)
2.Management of the digital photo database (a.k.a Digital Asset Management)
3.Manipulation of photo zones (areas)
4.Pixel-level photo and graphics manipulation
Now let us look at what each program does...
•Photoshop started as #4 aimed strongly at graphic artists, but then later...
•In creating Creative Suite (CS), Adobe started with Photoshop module as Super #4, and added Adobe Camera RAW module for #1, and Bridge module for #2, and also beefed up the photo manipulation with #3. Bridge has less robust features for #2, compared to what LR can do.
•Adobe bought rights to RAW Shooter as #1, and fleshed it out with #2, to create and launch Lightroom 1. It later added #3 capabilities (Brush) in LR3. Note that LR lacks #4, and most folks use simpler programs like Elements or Paint Shop Pro for pixel-level editing needs, to supplement what LR can do.
So when you consider 'LR or CS?', one needs to carefully consider the breadth of software capabilities that will be needed.
The most commonly used RAW convertor on POTN is Lightroom; the RAW conversion within CS is #2. https://photography-on-the.net/forum/...6#post13665896
I don't know if anyone has done a 'which most commonly used pixel editor on POTN' thread.
CS is far, far more expensive than LR, in both the initial purchase and later in updates. LR updates are typically $99, while CS updates are considerably more expensive...per the Adobe site, if you currently own CS 5.5, upgrade to CS6 Design Standard costs $275! The fact that you initially might have purchased CS at a student price has absolutely no bearing on the cost of later upgrades.
If you own LR, you can easily add pixel-level editing capabilities (like Photoshop has) via inexpensive programs like Elements or Paintshop Pro,
