Value Viewer – revisited
A while back I reviewed a handy little iPhone app called ValueViewer. It helps artists (especially plein air painters) to see, to simplify the number of values (white, grey, black) in a scene. I liked the concept but thought that the original app had some serious flaws – primarily that one couldn’t save the image that the app produced.
On April 20th, 2012, version 2.1 of ValueViewer was released. It is a winner! One can now open any image from the iPhone camera roll (or take a new photo on the spot) and most importantly save the modified image back to the camera roll. From there the image can be uploaded to a computer and printed out. This is of great value to me for generating a reference print to use in the studio.
The user interface is a bit different from the original version and maybe not quite as intuitive but with the built in Help info and a bit of practice I think it will be fine.I like that one can flip from portrait to landscape format, adjust the window to any standard canvas size and to zoom in or out with simple finger action.
My only complaint is that one can not select the number of levels displayed. You can select gray scale (“infinite” levels), Notan (two levels: black and white) or three levels (white, gray and black). I would like to be able to choose, say 5 or 9 levels. The app does allow one the flexibility to adjust the mid-point on the value scale and the range of the gray region.
In conclusion, this version (2.1) of ValueViewer kicks the app up to the “very useful and recommended” level.
