Two Images

by EBTRR in Addons

Two Images (short: TI) is a simple Add-on that allows you to compare two images on the x or y-axis through a slider.

You can compare images, render slots and the viewer output with each other.

The Add-on works currently with different Color Spaces of the Image Settings (and most of the View Transforms) but only with sRGB in the Display Device Settings of Color Management.

A separate Version for users of ACES (for example: OpenColorIO ACES) has been released. The focus of the ACES Version is to compare Render Slots. Like in the normal Version, when you change the image View Transform, you have to reload it by pressing Comparision or pressing the render button again.

Name: TI_CI_1_0_x_ACES_0x.zip

If would recommend to use Version 1.0.5 but if your PC needs 1.0.6 install the newer version.

ACES support from OpenColorIO goes until 1.0.5, although you can adjust the adjustment values for standard version for sRGB.

The same goes for every other Color space usually you need only to adjust Multiply a few notches. (Sometimes Gamma and Linear too)

1.0.6 uses a smooth pixel interpolation.

Tested Platforms: Windows, Apple Intel

Version: 1.0.6: Image Editor -> Menu -> Image -> Two Images

Current Interface:

Usage:

After selecting an image in the Image Editor, you can activate the Add-on:

Select an image for comparison:

Change the axis:

Change the Position:

If you have Render Result selected, you can change the slot and compare different Render Slots or Slots with other images:

Change the Color of the Separation Line:

Color Correction and Adjustment:

Partially for Screens Calibration.

Saturation and Value for a fast test of different looks.

Linear for Linear Interpolation of Pixels.

Fast Selector:

Replace the Image with the Render Result or Viewer. The last selected will appear blue even when you change your image selection. You simply have to press it again if want to have for example the Render Result again.

When a Slot is empty:

A warning message if a slot is empty.

Two Versions:

The Add-on has two Versions. One as a separate Category in the UI (TI) with the name TI_CT_1_0_5.zip. (Version Number will change in the future)

The other with the name TI_CI_1_0_5.zip which is in the image category.

Both are the same, only different categories. (Request from different customers)

Limitations:

Suppose the Viewer (Composition Node) has a different scale (Composition Node: Scale) instead of the original scale of the input render layer. In that case, it will appear smaller or larger in the original space of the Image Editor. If the Viewer Node is empty, Blender's default representation is loaded (invisible image). Simply check if the Viewer Node has an Image before loading it.

This limitation comes from Blender's representation/projection of the Viewer in the Image Editor.

If you update the Viewer, the Viewer Node is selected in the interface of TI. You must press Comparison to deactivate and then activate the comparison or reselect the Viewer Node in the associated area.

If the image appears black, move the position, and it will get reloaded.

If you are a User of ACES, a complete installation is required.

Depending on your GPU, the colour between the original and the created has minimal difference. (Small Adjustments usually help; usually unrecognizable)

Depending on your distance, the image has a small offset.
