This shows probably the biggest drawback to this “slit scan” technique of capturing a panoramic image. Here is what happens if someone walks past you while you’re shooting. Click image to enlarge.Įxample 2 of a panorama shot using the iphone 4s hidden panorama mode. Example 1 of a panorama shot using the iphone 4s hidden panorama mode. Here are some examples of panoramas that we shot. The saved panorama size is somewhere around 6122×2852 pixels which is about 17.45 megapixels. In fact, almost every “super-wide” or 360-degree image needs a considerable amount of exposure blending and unsharp mask in order to improve both local and global contrast in a way that is seldom necessary in “normal” photographs. Unless your sensor has very high dynamic range (and again, this iphone panorama mode seems not to be using any HDR, tonemapping, or exposure fusion techniques) then locking the exposure usually results in a rather flat image with large portions being completely under- or over-exposed. This has strengths and weaknesses – while it’s nearly always good to lock the white balance when shooting a panorama, it can actually be beneficial NOT to completely lock the exposure, especially on “partial panoramas” (images smaller than 360º in width and 180º in height) – it’s a fact that when you’re shooting such a large area, there will always be large variations in the lighting of the scene. This does however give some very strange geometry to the image, where straight lines are not straight, but neither are they curved in a predictable (as in a “true panorama) way – I’d personally rather see more stitching errors than crooked lines, but I think this is up to individual preference.Įxposure is also locked, and probably white balance also (though I didn’t check). The final image has far fewer “stitching errors” (seams where two individual images are blended together) because there isn’t much being really stitched, rather the image is sort of “painted” across. Since you don’t actually have to move your phone at a predefined speed (this would make it basically impossible to use), the panorama mode is clearly utilizing the phone sensors to determine how often to take a vertical strip from the camera buffer and add it to the panorama. It seems that this iphone panorama mode has all the shortcomings of such an approach: it only works moving in a specific direction, and moving objects (ones that are moving either with or against the direction of shooting) become very weird in the final image. How does it actually work? Well it seems to be essentially a “slit scan” panorama: imagine if you used your flatbed scanner to take a photograph, by moving it slowly from left to right.

We all knew it was coming, didn’t we 🙂 It was with some disappointment that this feature, rumored to exist already for months, didn’t appear in the iPhone 4s release event. Now, I’ve go to say how exciting it is to see this panorama mode finally. tap “options” and activate panorama mode 10. under the line that says DiskSpaceWasLow, putĮnableFirebreak 5.
