Oh, I can understand now the thing about projects, albums and folders than to that link you sent Albums are equivalent to Quick Collections and Smart Collections in LR. Since it's not possible grouping images which are stored in different folders ('Folders' interpreted by LR is the same than in Finder), LR provides the Quick and Smart Collections to do so, without the Aperture Folders thing.
I do love the way Aperture interprets the image and all the ways to edit them, speciall color correcting by using curves by channels or just toning the image. I found that way is the equivalent to Split Toning in Lightroom, but achieving better results in Aperture. I miss the ability to use blending modes, like it happens with Capture NX, because by using channels in Levels or Curves, it also affects the luminosity of the image plus the color, and it should affect only color (like setting up curves to the color blending in Photoshop). I also miss the absence of the Graduated Filter that LR and NX has in Aperture, the vignetting effect as well. In Aperture, is too basic. Also, the Noise Removal tool is not very well developed, nor the sharpening. there is no way to correct lenses aberration such as barrel and such as well and the whole interface is quite messy and non intuitive.
I also find the Metadata Feature section of LR quite helpful in order to see any kind of useful information related to the whole Catalog of pictures or just the selected folders. You can know how many pictures you took with a wide angle lens, or with a telephoto, etc, in order to do a very accurate analisys of what you more frequently do. And it's even customizable by adding new cells. All this organization is done automatically by using the Metadata of the pictures. I found, for example, that I rarely use the 14-24mm and mostly the 24-70mm in my landscape photography. This allowed me to know that I better take with me just 1 lens instead the other one. It also helped me to know the exact hour of the sunset where the pictures looks better, but shamely, the Metadata Feature in LR doesn't allow adding a cell of time, but in each thumbnail is displayed (which is also customizable).
Here is an snapshot:
I personally like statics a lot, because it allows me to understand myself much more by looking for patterns in my life and therefore, predicting what should I buy or change in my personal life. I have taken great shot with the wide angle lens, but just a very few, so it's not worthy for me having such lense or, I should try to understand it a bit more. By loking at all the pictures where I used the wie angle, I selected the best ones, then I figured out why are the best, so that way I could understand when and how to use it, but my comprehension aboutthat lens is not 100%, and I'm not talking about the basic reason of using a wide angle (capturing more scenary), but which kind of feelings can be created with it.
I found that wide angle for landscape tends to create too much empty space in the ground, so I tend to focus more on the sky. Also found that it usually makes the cmposition with a tendence to put the horizont in the middle of the frame, as for the positive ones, I found it quite nice for centering a subject which has 2 points of fuge. Because of this self observation, thanks to the easiness that Lightroom provides by categorizing the pictures for just looking at the ones taken with the wide angle lens, I have figured out that I have to improve my composition and comprehension of space if I want to use the wide angle lens in a worthy manner.
