Poster Printing vs Undertone Tuner

With this app, an image can be printed as a large poster. The image is divided into several pages for this purpose. After printing, the white border must be cut off in order to assemble the individual pages into a poster. A thin border line is printed to help with the cutting. The pages are numbered barely visible at the bottom left to avoid confusion when putting together the poster. Printing of page numbers can be deactivated in the settings. The image is automatically rotated to better fit the paper size to reduce the number of pages needed. In the free version of this app, ads are displayed and the size of the poster is limited to 60 centimeters and 24 inches. The size limit can be extended with a one-time in-app purchase. The ads can be completely removed with another one-time in-app purchase. Please note that very large posters require a large number of pages to be printed. Please check the entered size in order not to waste paper unnecessarily.

Undertone is a precision tool for tattoo artists and clients. Fresh tattoos often come with redness and inflammation that can distract from the actual work. Undertone removes that redness while keeping the skin tone and tattoo detail intact. How it works: Select or take a photo of a fresh tattoo. Paint over healthy skin near the tattoo to set a reference tone. Tap Apply. Undertone uses Lab color space analysis to neutralize redness across the image. Fine-tune with Strength, Threshold, and Brightness sliders. Use the Exclude brush to protect specific areas from correction. Save the final image at full camera resolution.
