As Lello has joined the band of NX users but is finding it harder to understand than Photoshop I thought I should do this post.
I have found far more info in the Help file than the instruction book. Also well worth a look at Nikons Capture NX site. Link ......

I was going to post a simple start guide. A run through this thread suggests quite a bit of info but not in any sensible order for someone just picking up on this program. I will add some more info with screen grabs to make it simple, but with a four a day limit it will take time to cover everything.
To date I suggest this thread is read through in this sequence as there are lots of explanitory graphics.

'D' LIGHT
Post #29 a graphic explanation of 'D' light which is in Base Adjustments. Refer to image 4 from post 23 for its location in the edit list.
For me the big buzz of NX is control points. You would be amazed at what you can do with these and they work on NEF's, Tiff's and Jpegs. Quite a number of posts here deal with this and I list them in a suggested order - least compex first. Play pics for this - I posted 2 play pics that are quite large in Post #27.

Probably the biggest difference's I have found when compared with Photoshop is that you can step back at any time using the edit list without loosing anything else you have done. To turn an action on or off simply click the appropriate tick box. You can use the same to fine tune any previous edit action. The most I have had on the edit list is Base Adjustment, Levels & Curves, B/W/N Points and 54 control points all of which had immediate access for modification. I also find NX curves so much easier than Photoshop, as the action box is live alongside the image and any correction is in REAL TIME on the whole screen image as you move the curve.
