HDRinstant User Guide: Lightroom® Plugin

HDRinstant plugin integrates with Adobe Lightroom®. This plugin will allow you to capture the best frame of your video, enhance it with HDR and retouch it directly in Lightroom®.

If you have not done it yet, download HDRinstant plugin here.

I. Shoot your video

  • Resolution

For best results we recommend filming in 4K.

  • Shutter speed

The right shutter speed will depend on the speed of your subject’s movement.

If the subject is moving fast, we recommend using a high shutter speed to freeze the movement. For example, when filming dancers jumping in the air, it is better to set your shutter speed at 1/250 of a second.

If the subject is moving slowly, we recommend using lower shutter speed. For example, when shooting passengers, it is better to set your shutter speed at 1/250 of a second.

  • Number of FPS – Frames Per Second

The number of FPS will depend on the speed of your subject’s movement. The faster the movement, the higher the number of FPS should be.

If the subject is moving fast, we recommend 60 to 120 FPS.

If the subject is moving slowly, we recommend at least 30 FPS.

  • Exposure settings

We recommend working on “Manual” mode, with an exposure compensation of -1, to make sure not to overexpose the highlights of the scene, and the ISO value set automatically. HDRinstant eliminates the noise generated on the image by a high ISO value.

II. Launch HDRinstant plugin from Lightroom®

1. Launch Lightroom®

2. Go to your video’s catalog and select it.

If you have not imported your video into Lightroom® yet, this guide will show you how to do it.

3. Click on File > Plug-ins – Extra > Run HDRinstant. Your video opens directly in HDRinstant.

III. Select the frame you want to process

Once you have uploaded your video, the first step consists in selecting the frame you want to extract and enhance with HDR.

1. Adjust the speed and brightness of the video. Double-click on Brightness to reset it.

2. Select the best decisive moment with the help of markers, zoom and sharpness tools

    • To help you select that best moment, you can mark up to four different frames. Pause the video on a frame that you think could be a good candidate, click on a marker and it will appear on the playback bar. To view marked frames again, just click on their respective marker on top of the payback bar. Right-click to delete a marker.
    • If you want to zoom in on an area of the image, select this area, right-click and click on Zoom in. You can pan the area you zoomed in by moving your mouse while holding down the right button.
    • To get the sharpest image, you can use the sharpness checker. This tool suggests sharper frames from the neighboring frames of the one initially selected:
      • If you want the sharpness search to be carried out by considering your entire image, right-click on the image and select Search sharper frames – Full.
      • If you want the search for sharpness to be carried out on a particular area of the image, select that area, right-click on the image and select Search sharper frames – Zone.

IV. Define the settings to process your image in HDR

Once you have chosen your frame, the second step is to define the processing parameters, from the HDR Enhancement section.

  1. Choose the processing speed from the drop-down menu.

The processing speed is the computing time required to process your HDR image. We recommend trying Fast first: some pixels blocks may appear where there is movement. If it is not satisfying enough for you, then try Medium: it is a good compromise between speed and quality. Slow makes the quality even better, but the calculation time will be longer, especially if the image contains a lot of pixels.

    • The default processing is done in CPU. If your machine has a GPU, we recommend using it as the processing will be more efficient.
    • To do so:
      • Open the Settings
      • Go onto the Hardware tab:
      • Check the box Use graphics processor.
      • Select the GPU of your choice from the drop-down menu. When possible, we recommend non-Intel graphics processors to get a faster processing time.
      • Note that if you have selected a GPU, you won’t have to select the processing speed.

 

2. Define the number of images to stack in the Stacking window section.

HDRinstant technology uses a high-end technique of image stacking in order to improve image quality and reduce noise. We recommend trying with the default setting first. If the final result still contains noise, you can increase the number of neighboring frames before and after your selected image. However, make sure that the number of FPS is high enough for the neighboring frames have to be similar to your initial selected image. Also note that the higher the number of stacked images, the longer the processing time will be.

3. Select the anti-ghosting option in the Effect to apply on moving subject section.

This tool allows to increase or reduce blurs from moving subjects. When selecting High antighosting, your moving subjects will be sharp. A long exposure simulation will allow you to get an aesthetically blurred on your moving subjects.

4. If needs be, increase the Movement amplitude

If the movement of your scene is very fast and/or of great amplitude, some artifacts might appear on your final result. If so, you can process your image again using a higher Movement amplitude. You can change this parameter from the Settings:

    • Go over to the Stacking tab and increase the Movement amplitude

5. Click on Process.

6. You are asked if you want to save those processing setting. By clicking on Yes, they will become your by-default settings.

7. If you are satisfied with the result, click on OK and save your image. It will be imported into Lightroom®. Several formats are available.

8. You can go back to the video to select an image and start a new processing. If you are satisfied with the result, close HDRinstant.

V. Edit your photo in Lightroom®

  1. Select your image in the Lightroom® Library module.
  2. To retouch your image, click on Development in the top hand-side to switch to the Development module.
