A spot under the sun.

Picci Picci is a colour correction tool, that screens the RGB graphs of any image you upload to it. With artificial intelligence and intuitive technology, you are able to automatically balance missing colour spectrums and abnormalities, bringing back the true colours of your image.

Whether your device isn't a professional camera, or if the scenery of the image has a dominant colour or even bad lighting, our tool will help you fix it and more !

 

Device issues

Bad lighting

Dominant colour

Our tool will do the following:

1. Import a picture

2. AI corrects colours based on "flatlines/clippings" and "missing/full spectrums"

3. Use RGB graphs to adjust to your personal preference

4. Adjust brightness, exposure, sharpen and contrast

5. Save your new image

Now you're ready to take it to the gram. 

Colour Correction

  • First we have to understand RGB Graphs, on the X axis input dark (0) and light (255)

    On the Y axis, output dark (0) and light (255) 

    By simply adjusting the total input range (0-255) of colour, we are able to bring back colours that had been lost due to Reds being dominant, and the lighting being low.

    This is what our tool is looking to automate, then you can then make more changes according to personal taste.

    When you use a filter or vibrancy or anything similar, you will automatically lose the "real" colours of the image. Our tool aims to do the opposite and recover said colours. 

  • In the example of a sunset picture, Reds will have a full spectrum, with a small corrections:

     

    If you look carefully, on the left (dark) there are empty values, so we will close the handle to where the first value begins in this case at 4 instead of 0. 

    On the right (light) you have an abnormal spike, which we will correct by reducing 255 to 253.

  • Where it becomes more interesting:  Greens that are missing values in the light side (right) and the same for Blues.

    This is where the magic happens, because of the dominant red and low lighting of the picture there are not enough light blues and greens. 

    We adjust it by closing the handle from 255 to 235. For blue, it is even more.

  • My idea is to try not to over-correct and just do what seems most natural.

     

    The science behind is quite simple, "empty" or "full" colour output values are likely unnatural and will need correction on the input value. Often occur because your device is more likely to have a hard time interpreting a colour that is close to white/black. Unnatural "spikes" are something that might need correction too.

     

    Graphs that are "shifted" towards one side, are missing a spectrum due to lighting or dominant colour and will require a major correction. Keeping in mind we want it to feel natural, if the correction is for example a value of 50, we want to add a "buffer" that will only correct it to 40.  (80-20 Principle)

RED

GREEN

BLUE

Each picture is unique and will not follow exactly the same reasoning as above, that is why our tool aims to adapt to any type of image and correct with 99% efficiency.

Licences for picture editing software are way too expensive and have few resources to teach about best practices, we help you do your job faster and educate about the topic

Most colour correction tools cheat by using vibrancy, exposure and even filters, on our side we want to truly give you the full picture and regain lost colours
