- Easy to blend or mix multi images by simulating the exposure effect of film ( including both Negative Mode and Positive Mode )
- Quick to make a collage by combining tens or hundreds of images
- Enable to concat or merge images by outputting a group of images that user selected from canvas

How to it works:
1.Drag many of images on to the app or top toolbar icon
2.Adjust ( scale/move/rotate/blur/exposure... ) the image

Details of principle and terminology:

What is a negative image ?
In photography, a negative is an image, usually on a strip or sheet of transparent plastic film, in which the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest.(from Wikipedia)

What is a positive image?
A positive is a film or paper record of a scene that represents the color and luminance of objects in that scene with the same colors and luminances (as near as the medium will allow). Color transparencies are an example of positive photography: the range of colors presented in the medium is limited by the tonal range of the original image (dark and light areas correspond). It is opposed to a negative where colors and luminances are reversed: this is due to the chemical or electrical processes involved in recording the scene. Positives can be turned into negatives by appropriate chemical or electronic processes.(from Wikipedia)

Each pixel contains four components of the red green blue and transparency channels.
In this app, transparency channels value is related to its summation of red 、green and blue value for each pixel.

1.Negative Mode
Opacity is negative correlation to value of its brightness for each pixel itself.

2.Positive Mode
Opacity is positive correlation to value of its brightness for each pixel itself.


The canvas dimension on quantity of total pixels will be limited within 400M.
For example, you can set the canvas dimension max up to
20,000 X 20,000
200,000 X 2000
400,000 X 1000
