The surface of the plate doesn’t need to super perfect the plate just needs to defuse the light so the camera doesn’t see any motive through the plate. This means that it is so close to the lens that it is totally out of focus. When shooting the opaque plate you place it directly in front of the lens. But I couldn’t wait to fix the problem until I returned from my trip, so I had to figure something out. In my case I didn’t expect the camera to show this kind of problem, so I didn’t bring my opaque plate with me. There are various versions of opaque plates you can use and they can typically be bought through your local photo dealer. Therefore, I only needed to do one reference file using these settings. Various versions of opaque plates availableįor this particular camera I am always shooting at f.5.6 and focusing on infinity. When shooting the LCC reference file you place the diffusing opaque plate right in front of the lens. Using the same light source may not be important for your camera/lens combination, but for others it may make a difference.įocus distance also have an influence but it’s not typically something that matters between focus distances of 5m to infinity, but it makes a difference between close-up and infinity as the light passing through the lens actually changes quite al lot between these focus distances. So if you are using natural daylight, then shoot the reference file in that light and if you are using tungsten, then use tungsten also for your reference shoot. You should also use the same kind of light.

The angles of incident light through the lens to the sensor needs to be exactly the same for the reference shoot as for the real images you want to fix. When shooting the reference file for fixing Color Cast in your lens/camera system, it is important to use the same lens settings as when you use the lens for your real images. In this case I only need to use the Color Cast functionality of the tool.

From this reference file Capture One Pro 7 can calculate the needed information to fix various lens/sensor related issues like: Color Cast, Dust Spots and Light fall-off. To fix an issue with Color Cast in your camera you basically need to shoot a reference file of a white opaque plate with the camera and the lens you were using. Once you notice it you see it all the time. It would really be a shame if such an image ended up on a white wall or framed with a passe-partout without having fixed the Color Cast issue. Here you can see the effect of fixing the Color Cast issue. The LCC Tool is located in the Lens Tool Tab.Ĭolor Cast in the image Color Cast removed by the LCC Tool Originally it was designed to deal with Medium Format Camera backs mounted on technical cameras where the angle of incident light through the lens to the sensor often can be very extreme and very different from when the sensor was calibrated at the factory for working with standard lenses. Enter the LCC Tool….įortunately Capture One Pro 7 has a LCC Tool (Lens Cast Correction Tool), which has been specially designed to deal with this kind of problem.

At the edge the WB is off with a difference of 14 between the red and the blue color channels. I have added the color readout pins to show the difference in WB between the center of the image and the edge. This was not something I had noticed before, but now with snow landscape images it was quite obvious.Ībove is the image in Capture One Pro 7 after import. My camera and lens were showing a classical Color Cast issue. No matter where I used the White Balance Picker to set the WB on the images, they would show a greenish/cyan cast toward the edges. I noticed that there was something not right with the ‘color’ of the snow.

Something not right about the “color” of the snowĬoming home from a beautiful day in Italy’s Dolomite Mountains shooting with a camera that I haven’t been using for snow landscape images before, I couldn’t wait to see the results in Capture One Pro 7. If you are having WB variation issues, the LCC Tool in Capture One Pro 7 will be the perfect tool for fixing the problem. Systematical variations will come outĮven though you don’t normally notice that your camera shows systematical variations in the WB across the image, it may become obvious in snow landscape images and you will want to do something about it. The snow in the image is like having placed White Balance cards all over your image and if you have any systematical variation of the WB, it will be very obvious to see. When shooting snow landscape images you are extremely sensitive to the White Balance (WB) in your images and to any tone variation in the ‘color’ of the snow.
