Stage 3 select remove ghosts closeup of the HDR with a hero first frame selectedĬloseup of the HDR with a hero third frame selected 32bit HDR with neutral mid point exposure shown A frame showing just two of the different bracketed exposures and the different people at waters edge in each See this example from a set of HDRs we shot in San Francisco on a Canon 5D. In a sense the lower LDR patch will be stretched in bit depth, this may not be a problem but it mathematically should be removed with 32 bit paint tools prior to export to an HDR format such as OpenEXR etc. However if you are aiming to use the 32bit file for some other VFX purpose – the “LDR Patch” should be removed as it will not be correctly graded when you access the HDR at different exposures. In your sole aim is to produce a nice tone mapped lower bit depth image then you will notice almost no difference and the results are likely to be highly satisfying. Of course there is no higher or lower dynamic range information for that unique part of the frame so the program is effectively putting a LDR (low Dynamic Range) patch in to the HDR. In the case that they are still visible in the hero frame this image of them will appear fully and unfaded in the final 32 bit HDR. In CS5 that person would be removed from all frames except the hero frame. For example if five bracketed shots are combined, then a person moving may show up as a 1/5th ghosted element (see below). This will look for erroneous data between the frames and remove it as part of the merging. In the new CS5 – multiple exposures are still bracketed together but you have the option of selecting a hero frame if anti-ghosting is turned on. Typically this could be someone walking or moving from one exposure to the next. Ghosting occurs when multiple bracketed images are combined and there has been something that has moved between shots. The HDR functions have been improved by the addition of a Ghost removal option and a simpler GUI. ![]() JDI stands for “Just Do It” – minor improvements, that individually are not major, but collectively add up to an improved user experience and a less stressful working day. There is an impressive new Content Aware Fill and Repair option and the team at Adobe has implemented a raft of JDI fixes. HDR production is improved and has been made simpler. In Photoshop CS5 there are many new features but a few really stood out as we have been testing it for the last several weeks. Plus we’ll explain and list the JDI fixes. In fxguidetv later this week we will profile the new AE, while in this article we take a critical look at Photoshop’s HDR and Content Aware functions. You can also use a Hue/Saturation adjustment layer to completely desaturate some of the squares, leaving them black and white.Today Adobe unveiled CS5 – there are multiple applications in CS5, but for many Photoshop and After Effects are the most vital. ![]() Finally, change the blend mode of the new adjustment layer to Color. Click OK to close out of the dialog box (CS3 and earlier). ![]() Select the Colorize option, then choose a color with the Hue slider and a saturation level with the Saturation slider. Click on the photo layer in the Layers panel to select it, then click on the New Adjustment Layer icon and choose Hue/Saturation. Hold Shift and click inside more squares to add them to the selection. First select the Grid layer in the Layers panel, then click inside a square to select it with the Magic Wand. Repeat steps 16-20 to select and colorize more squares. Step 21: Select And Colorize More Squares A few red squares have been added to the effect.
