The live crosshair reading seems almost too sensitive, with the numbers constantly jumping up or down 6 points regardless of how steady I hold the thing. Is there a way to reduce the sensitivity a bit or average out the readings over a second’s time? I get that it is simply being accurate, but it is an accuracy beyond my appreciation on a tiny phone screen.

One of my art teachers used to say if color was a yardstick, value would be 34 inches of it. If you can break an image down into just four values, you were already 90% ahead of the game. One trick is to load in a photograph, convert it to four values, and save it. Then use the target pointer to tell you what values to use I use a controlled pallet, so every color is premixed and tubed in nine values. That’s like doing all your work up front and with a tool like this it makes the whole process super easy . Paint simple flat shapes in four values, then go back over it when it’s dry, adjusting any values if necessary, and smoothing the transitions between the shapes. Voilà!

My wife is an artist and see needs to view a photo is black and white to see the balance between the two before she starts a pastel. More importantly, see needs the ability to adjust the black level to more than just 50/50. A painting with half the area black is not pleasing. Some scenes balance well at 30/60, or 40/60 or some value in-between. This app now has a slider that allows for such adjustment. It’s the only app for iPad that exists for iOS 11. Ann considers this app vital to her painting. Great job by the developer! She uses it every day.

I use this app to reduce my photos to grayscale and then play with the value levels to help me adjust an image for use in relief printing. It’s great! And it is definitely worth the 99 cents to have access to your photo library.Additionally, the developer provides good customer service. He actually responds to the questions and concerns of his users, which, in my experience, is something that is relatively uncommon in the app world.
