ARCPanel

ARCPanel is an extension for Adobe Photoshop that solves the pain of building luminosity masks.
Actively supported version is ARCPanel 3.0. It is free and works on Adobe Photoshop CC 2022 and later. ARCPanel Pro enables advanced functionality.
For older versions of Adobe Photoshop (2015.5 - 2022) you can use ARCPanel 2.2. It has a free trial for 7 days and has to be purchased afterwards. All features are always enabled. Is no longer actively developed and will not have new features added.
There are 3 tabs in ARCPanel: ARCMask, ARCRetouch and ARCSharpen
Clear the state and remove temporary panel channels.

Mask source is a base for all other masks. By default, Luminosity is used, but you can select other sources to generate, eg. Saturation masks
  • Luminosity – regular luminosity mask
  • R – luminosity mask for Red channel
  • G – luminosity mask for Green channel
  • B – luminosity mask for Blue channel
  • Saturation – mask, applying to most saturated pixels of the image

Hue range mask (or Color mask) is a part of source and is built based on already selected source options: Luminosity or Saturation.
Luminosity is used by default, meaning that colors will be selected based on their luminanse values. Selecting Saturation as the source will change color slider to select based on color saturation values.
After hue mask is applied it itself becomes the Source and can be modified by any masks – that means that you can select a range of colors from the image based on their Saturation values and after that select brightest of them by clicking Lights-3 on Masks
  • Color Picker – lets you pick a color from the image to build color mask
  • Color Slider – click anywhere on the slider to select a range, drag handles to modify the range. Click Build Maks or Cancel to apply or cancel color mask.
  • Feather and Boost - move Feather and Boost sliders to better control the selection.

Luminosity is a spectrum that is not limited to Lights 1-5 and other ranges. Luminosity range masks brings flexibility into luminosity mask creation allowing to pick the mask you need by just moving a slider.
Functionality is very similar to Range Masks from Lightroom, but in Photoshop, with the availability of layers, this gives a completely different level of flexibility.
  • Range picker - lets you pick a luminosity from the image and slider will auto select correct values
  • Luminosity slider - controlling two sliders, select any range you want. Having right-most slider fully on the right will give lights. Having left-most slider fully on the left will give darks masks. Having two sliders in the middle will give midtones selections.
  • Feather and Boost - move Feather and Boost sliders to better control the selection.

Paint mask is a special function, that gives a one-button shortcut to a widely used technique in processing.
Often we want to paint desired effect through a mask. Usually, this requires to:
  • build a mask
  • make a selection
  • hide marching ants
  • select a brush
  • set foreground color to white
  • select mask (set it black if it's missing)
All these steps are done automatically by pressing Paint Mask button. Panel will also conviniently show if there is a selection with hidden ants active at any moment.

Quick actions are small utility shortcuts that can improve your workflow speed
  • Clear – clears ARCPanel state, removing selections, channels and active masks
  • Quick Blend – when activated, disables preview and directly applies selected mask on the selected layer. Very helpful when blending images together.
  • Group with white mask – a button to quickly group layers with white mask applied
  • Group with black mask – a button to quickly group layers with black mask applied
  • Preview on hover – disables or enables preview on hover functionality

Infinite Color

One click on Infinite Color button generates a random color grading preset that can be manually adjusted. Keep clicking until you find a pleasing color combination and then tailor it to your needs. Feature works best for city and portrait images allowing to quickly get to film-like colors.

FREQUENCY SEPARATION

Build
Frequency Separation is a tool that lets you extract texture and modify it independently from other parts of the image. Main appliances: smoothening human skin, fixing lens flares, professional product retouching.
ARCRetouch previews both texture and tone(color), letting you select exactly the right frequency you need for your image.
  • Gaussian Blur gives more conventional results
  • Surface Blur works good in portraits
  • Median gives much better results and fine-tuning for product retouching.
Every method will generate extra layers for quick re-touching of low and high frequencies and a hidden Texture Boost layer to simplify work with skin.

Dodging and Burning is the main post-processing technique. Dodging is brightening, and Burning is darkening parts of the image.
Panel provides 3 Dodge & Burn techniques
  • Grey Layers – the most used technique – two 50% grey layers with Overlay and Soft Light blending modes
  • Curves – A bit emore advanced technique – 2 curves adjustment layers layered in Luminosity. Curves set the limit of dodge/burn to avoid clipping.
  • Automatic – Good for portraits. Lets you select Blend-If ranges for lights and darks – this allows to automatically update Dodge and Burn when underlying pictures changes

Free and easy way to make your image ready for web.

Sharpen

Whether you want to sharpen only current image or all images opened in Photoshop – ARCSharpen can handle it for you.
There are size presets for Instagram and Facebook that give you best image quality for social networks, but you are also welcome to set custom values with "Fit in" selected.
Clicking on "Sharpen for web" will sharpen opened files, but not save them.
Algorithm is a widely used step size sharpening: first image size is set to double the target, then image is sharpened, downsized to target size and sharpened again – this gives great results that both keep the quality high and make image look great in the browser.

Export

If you also would like to export files as sRGB JPG, click on Export checkbox.
You can limit size of the files to a value in kilobytes. During export, ARCSharpen will keep your selected width and height, but will pick a lower quality of jpg compression value to fit size that you want as close as possible.
Select the folder you want to save your images to.
Optionally, set Prefix, Name and Suffix. Prefix will be put in front of every file, Suffix will be put to the end. If you don't set a Name, original filename will be used, otherwise same Name will be applied to every file.
For example, with Prefix November_, Name Saxony, Suffix _Nightsky will give you filenames of November_Saxony_Nightsky_1 and so on, with number in the end increasing for each file. This also happens if when saving file with such name already exists.
Clicking "Sharpen for web and export", ARCSharpen will sharpen your images and save into selected folder.
