I would agree with Sandman but I would strongly suggest that you dont use the method on converting to B&W as described as this will no doubt cause you to be hugely dissapointed in the results when compared to what you could achieve in the dark room (no offence meant Sandman). The best way to create a B&W image from a colour one is by using the Channel Mixer. I have written a tutorial on my website (
www.peakoverload.com) that details this using Photoshop if anyone is interested.
The biggest problem with Photoshop is that it does look daunting if you have never used it before and a lot of people think that they have to master it all before they can use it. This simply isnt true. I have been using Photoshop since version 3 and am now running Photoshop CS (version 8) and there is still tons I dont know how to do in Photoshop.
In order to do basic editing in Photoshop all you need to learn are:
Levels
Curves
Unsharp Mask
Channel Mixer (if you want to do B&W)
Clone/Patch (optional)
For slightly more advanced stuff:
Using Adjustment Layers
Dodge
Burn
Masks
For more advanced stuff:
Pen tool
Advanced selections
Blend Modes
From there on you just learn stuff as you need to.
The other big problem with Photoshop is the price! It is expensive but if you are serious about image editing it is by far the best program out there. That said Paint Shop Pro does give it a run for its money but personally I just really dont like the user intereface and find it far more confusing than Photoshop but then thats probably got more to do with the fact that I've used Photoshop for years.
If Photoshop is not in your budget than Photoshop Elements does offer a lot but, again probably because I've used the full version for so long, there are a number of key tools that are not avaliable which I find make it really frustrating to use. That said once you have learnt Photoshop Elements learning Photoshop is a cinch.
Another one to consider is GIMP which is a free editor that is very powerful, some say as powerful as Photoshop. Again I must admit that I dont like it but I know lots of people who love it, I just find it a bit too confusing.
The problem with some of the 'budget' applications is that they are very limiting. For example they may have a red eye removal tool but you cant specify the colour of the eye or feather the selection around the eye to make it look more natural. Other times they effectively have just a warm up or cool down my photo option which just works of presets rather than actually let you specify exactly how you want it to look. The advantage is that they are very easy to use, the disadavantage is that they dont do it very well and take away some of the control.
