Computers: Mac - every OS from 8.6 through Lion. Oldest computer is Pismo from year 2000, newest is MacBook Pro. Favorite is Powerbook G4 running Mac OSX 10.4.11 (Tiger). Most used is Mac mini running Snow Leopard (10.6.8).
Photo Editors: SIlkypix 4 & 5 ; Nikon Capture NX2, Graphic Converter 8.2; CS2, on Snow Leopard.
Live Picture 2.6.2 and PS 5.0 in Mac OS 9.2.2 in Classic mode under OSX 10.4.11 (Tiger), Graphic Converter 6.7.
Filters: DXO film pack; Flaming Pear Design Sextet, Snapseed.
Work Flow: All JPEGS and RAW go into SIlkypix for global adjustments (CA removal, WB and exposure ) and saving to uncompressed TIFF full size. This reduces JPEG artifacts that are caused by the camera compression of the image.
Then, if the image is noisy it goes to Nikon Capture NX2 for noise reduction because it has a good algorithm and the noise suppression can be applied to specific tones.
Then saved as TIFF (and often to NEF so I can go back to the adjustments I made) and transferred by WIFI to my Powerbook. The TIFF is converted to IVUE format in either PS 5, or in Live Picture utility.
The file is opened in Live Picture and here I do all the editing, with sometimes a dozen layers. The layers are either 32 bit or 48 bit, so that I never get any banding artifacts (always a problem with skies in 8 bit mode) I can build the file to any size I want, any resolution. I build the file to a TIFF at the size I want for the LI site. Then I transfer the file by WIFI back to the computer running Snow Leopard and do final conversion to JPEG to embed the colors.
I compare the pictures in the browser with the picture in my LP editor.
Live Picture is not a pixel editor like all other software commonly used. The image is adjusted using mathematical routines which are applied to the screen image and used later to build the new image from the adjustments. The original picture may be an 8 bit image, the dodging and burning, blurring and sharpness, color adjustments, local contrast changes are all 32 or 48 bit layers. All the adjustments made are applied mathematically to the screen image which can be any size (zoom 1000% +) and you don't see any pixels. When you have finished editing, you build a new image to the size and resolution you want - postage stamp to billboard.
All the editing is done using brushes which can be quickly adjusted in size from pin head to the entire picture size. A Wacom tablet is pressure sensitive to allow the brushes to apply changes gently, or hard, as water color, or pastel. And you can't tell where the brushes have been because the brushes have such soft edges. I can brush sharpness and blurriness on the same layer, also blend, dissolve, and smudge. I can make changes to areas of a specific color, saturation, and luminance, and adjust any of those independently in HSV mode. All edits can be undone, at any time within the next few years on any Mac computer since 1997 which uses a PPC chip (not Intel.) So images I made in 2000 can still be edited and all the editing adjustments I made then, can be viewed and modified in 2013. I can make an unlimited number of versions of any picture and all the edits are stored in very small files. The original captured picture is always preserved.
For cataloging pictures I use Cumulus 5 for Power PC (not for RAW images) and Graphic Converter which uses the computer folder heirachy, and so is always up to date.
I sometimes use PS in L*a*b* mode for color adjustments before I go to other editing.
It is really good for low contrast picture.
I don't use either of my Lion computers for photo editing (screen is reflective and your clothing colors impact the image, so does the room color, light through the window and so on) - great for web, though.
