Whether Exposure Fusion is a form of High Dynamic Range Imaging (HDR) or not depends on how you define HDR. If you have a broad definition of HDR Imaging that includes techniques that have been around since the 1850s when Gustave Le Gray first used parts of two differently exposed images to create photos of seascapes, then Exposure Fusion is a form of HDR. ...

Whenever you compare in-camera to post processing you end up with exactly the same advantages to post processing: Control Lightroom for photos or photomatics for HDR has lots and lots of options and sliders, there's no way you can get all of them into a camera-size interface - and even if you could they are things you want to change and experiment with ...

HDR and exposure fusion (as done by a tool like enfuse) are two different ways of attacking the same problem, but exposure fusion is NOT an HDR technique and does not require HDR file formats or tone mapping. Enfuse's main algorithm does not involve remapping tones along a larger dynamic range, but selects and weights values from the original pixel data of ...

Exposure fusion means blending of differently exposed images. This resulting image will not have an expanded dynamic range, but is basically a composite of the dark parts of the overexposed image, and the light parts of the underexposed one. HDR on the other hand is an image which was created by combining all the data of the source images, resulting in an ...

"Exposure Fusion" just refers to a certain type of the tone mapping of an HDR image. It doesn't include all HDR tone mapping algorithms, and is rightly tagged as "HDR".

All but the most trivial panoramas or HDR's will benefit from manual post processing, eg. removing ghosts or twiddling with the tone mapping. If you let the camera do it, you're stuck with the JPEG it produced, with no chance to correct anything. Baiscally, the argument for manual panorama and HDR production is the same as for RAW vs. JPEG, only more so.

I can think of a few reasons why an intelligent camera still wouldn't be as good as a competent photographer: Where would the camera lock exposure and focus? It would have to be at the beginning of the panorama, which presumably doesn't contain the most interesting/important part of the final image so it's quite likely that focus and exposure would not be ...

How precise are the inertial sensors? Programs may have to align images based on content, but that is very accurate, plus programs offer different blending algorithms and many projections to choose from as needed. Not to mention that existing algorithms improve and new ones are introduced. That's what manual mode is for. Please explain how a camera can ...

Bear in mind that the iPhone can also record video, which is usually at least 24 frames a second. Many cameras these days can record video at 60 frames a second. 20-30 shots a second should be a piece of cake if you have enough processing power or choose a lower resolution. There's nothing to slow it down, really. The limit of 10 images a second is ...
