![]() ![]() I'm using these 7 images taken from a bridge in Chiswick, West London.Obviously taking pictures from a nodal point rotation base will help a lot, but the good thing of this technique is that you can use different angles taken from different positions and also using different focal and different film backs from various digital cameras. The pictures that I'm using for this tutorial were taken with a nodal point base, but they are not calibrated or similar. But the power of this method is that you can use it with HDR footage recorded with a Blackmagic camera, for example. This method is much more complicated and requires more human time than using ptGui or any other stitching software. It can be composed using only 2 images or maybe 15, it doesn't matter. I'm talking about blending different images or footage (video) to create a seamless panoramic image ready to use in any 3D or 2D program. I'm not talking about creating equirectangular panoramas for 3D lighting, for that I use ptGui and there is not a better tool for it. In this post I'm going to explain my methodology to merge different pictures or portions of an environment in order to create a panoramic image to be used for matte painting purposes. If shooting artificial lights take HDR samples of each individual lighting source.Write down measurements of the scene, specially if you are shooting interiors.Take backplates and ground/floor texture references.Place the Macbeth chart 1m away from tripod on the floor and take 3 exposures.Keep half of the grey sphere hit by the sun and half in shade. Place the aromatic kit where the tripod was placed, and take 3 exposures.Shot 5 to 7 exposures with 3 stops difference covering the whole environment.Shot slate (operator name, location, date, time, project code name, etc).Read histogram and adjust neutral exposure if necessary.Plant the tripod where the action happens, stabilise it and level it.When shooting textures for scene reconstruction always use a Macbeth chart and at least 3 exposures. ![]() When shooting backplates for look-dev use a wide lens, something around 24mm to 28mm and cover always more space, not only where the action occurs.Don’t put anything on your feet or around the tripod, you will have to hand paint it out later in Nuke. Try to plant your tripod where the action happens or where your 3D asset will be placed.Plan the shoot: Write a shooting diagram with your own checklist, with the strategies that you would need to cover the whole thing, knowing the lighting conditions, etc.Have a small cleaning kit with you all the time.Have more than one CF memory card with you all the time ready to be used.Extra camera adjustments would be required at the moment of the shooting, but try to establish exposure, white balance and other settings before the action. Set-up the camera, clean lenses, format memory cards, etc, before start shooting.Leave cables and other stuff in the van, don’t carry extra weight on set. Try to carry only the indispensable equipment.Witness camera and/or second camera body for stills.Material samples (plastic, metal, fabric, etc). ![]()
