I will do the crops and post them.. How did you do the squares side by side? use layers in phtoshop? I really like the way your persented them.
I open each of the four RAW image files sequentially, each in its own "floating window" (PS CS6). I resize one of the windows to the relatively small square that you see, which becomes a size template for the other image windows. Then I resize the others to match by moving a big window on top of the small one, lining up the top-left corners, and then dragging the lower-right 'resize' control on the big window up and left to match the bottom-right corner of the 'template' window. Then I move the resized window to a new place (e.g. right, or down), and do it again with the other two big windows. This is a piece of cake on my relatively new computer, but it took a long time on the one I owned previously (due to crazy-long lags in dragging a large window across the screen). If it loads your computer too much, then first do a guesstimate resize on the 'next' window, then move it over the template, and adjust size as required.
I size and move the "Navigator" window to just below the group of four panels (i.e. windows), and use it to help position the locations that I want to highlight in the images. I set each small window to the 100% view (i.e. each pixel in the image file maps to a single dot in the display monitor), using Ctrl-Alt-0 (zero), and then use the Navigator to position the panel within the image. First, select one of the panels by clicking on it, and then click in the Navigator window where you want the centre of the panel to be located. I attached a screen capture of one of my "working" files with the Navigator still attached to the four-panels, below. After a bit of practice, it's really easy to set the four panel locations very quickly. I can move the mouse to each panel and back to the Nav window, without shifting my gaze from the Nav window. Once the panels are all roughly positioned, then I use the up/down and left/right slider bars on each panel (window) for fine tuning. If you click on an actual arrow, the window moves only a small amount. I find it easier and more precise than moving (dragging) the slider bar thingy. Only the "active window" shows these controls. In the attached example image, it's the ZE 18/3.5 panel, at the bottom right of the four-panel matrix.
As I mentioned in the test thread, I compare at least three images for each test condition (lens, aperture, and scene) to get the 'best' one. I use basically the same process as described above to put up three, small 100% crop windows, and then compare different parts of the images at 100%, to decide which one is the best. I simply close the two that aren't selected, and then save a .psd version of the 'best' one. This makes it easy to quickly figure out which one I want to use, if I revisit the files for some reason. When I save the file, I use a name that includes the lens and aperture (e.g. "EF 16-35 f2p8L IS at f8"), as a prefix to the original file name that came from the camera. I don't use 'dots' in the filename (and so "f2p8"; uses "p" for "point"), and you can't use "/".
Once I have the PS CS6 multi-panel screen setup the way I want it, I grab a snapshot with "PrtScn", paste the image into IrfanView, crop the image in IrfanView, and save the file. If this .jpg file is too big to upload to FM (> 540k), then I open it in PS CS6 and resave it with a lower "quality" (i.e. more compression). Many of the 'original' 16-35/4L IS image capture files were a bit larger than 540k, and so I resaved them at "quality 11", where 12 is the maximum quality (least compression). I use PS CS6 for this, because it gives me the best controls, and I can do it really fast with keyboard short cuts - I probably could make an action to do this... but it's plenty fast and I usually do it on one file at a time (some don't need recompression).
When I have only three comparison panels, I put the Navigator window in the "fourth" location. When I have two comparison panels, I put the Navigator centred below them. In the past, I've included the Navigator window in my four-panel posted images, but I didn't for the 16-35/4L IS comparisons because I like to save the image-comparison files with as little compression as possible, within the 540k limit, and so I cropped off the Nav windows at the IrfanView stage. The example "working file" attached below was 674k in size, before resizing it to 539k using PS CS6 at jpeg save quality = 11 (that was close).
That's about it.
