    Re: Continious Bolt

    Is the bolt in all four images or is it effectively a panorama with the bolt in one of them?

      Yes the bolt is in all of the separate images, but when stacked or panorama'ed (!) the bolt is only shown once.....

        [img]

        Trying the HDR stack in LR, shows just one bolt position



        Trying the panorama stack in LR...again just showing the bolt in one position...……..

        Roughly the same result in PS...….

        I used Procap to record the series of about 15 images...……..

        My hopes were to have the bolt shown in several positions...……..

          So its the same scene with the bolt in a different position in each scene then PS is your best choice.

          (I am on a Mac so the menu options might be different on Windows)

          If you have the images in Lightroom
          Make sure you are in Library Mode. Grid view.

          Select all 4 images.

          Then right click and select > Edit In > Open as layers in Photoshop

          This will open PS with each image in a different layer.

          Then in PS

          Select all four layers
          Then from top menu
          Select EDIT > Align Layers


          Then all the 4 images are aligned.

          The next step is a bit of a pain but will give you what you want. Make sure you are using a soft edge brush

          Starting with the top layer use the Erase tool and erase the area where the bolt is on the next layer down, and where it is on the third and four layers, then the bolt from the second layer should be visable in the image.

          Then select the second. Layer and erase the area where the bolt is in the third and fourth layers. Then repeat for the final layer.

          If you are OK with using masks you can do the same thing with masking.

          Hope this makes sense.

                  Re: Continious Bolt

                  Wornish already did the solution to it. I just did it but I use Affinity Photo on a PC. I just stacked 2 photo at a time, export the result then stack the next to it and so on till all the arrows were there. It was all automatic.

                    If you are in the mood you might find turning Deghosting to OFF in lightroom will stop it removing the bolt too. I might be wrong though

                        PS does need some practice to get the best out of it. What Henry did made it a lot easier by doing just two consecutive frames at a time. Combining them and then adding the extra frames in sequence one at a time. Affinity Photo and some other apps also support working with layers and that's the key to solving the challenge.

                        Stacking won't work because it typically averages out the individual pixels at each point in the image. Stacking in PS can be tweaked to use other functions like select the maximum or minimum value of a pixel from a stack of images. In fact, it is a technique used to remove unwanted people in a shot of a target that's fixed like a house where tourists are moving in front of it, which is the exact reverse of what you want to do.


                        Interesting though to see the end result and he did miss the target

                            I'm glad it was interesting. I've played with it in the past when I've had people moving through panoramas while I was shooting. It can do a good job of removing things, I guess all the programming is trying to stop things appearing several times.

                            I'm no longer a photoshop user but from reading things about stacking shots to create long exposure fakes - you'd import all the images as layers, use the Auto Align to get them in the same place (might be a smart object?) then paint a layer mask that would only show through the bolt on each layer?
                            Last time I did something with GIMP it didn't have the auto align which made a handheld burst so fiddly I gave up.
