HDR Close up photography on Galaxy S2 Camera

Below is an example of closeup photography using the Galaxy S2. For this image, I've taken a photo in full resolution, cropped the area I wanted to get a close-up, and post-processed in Photoshop using HDR settings to subtly enhance the colour.

As previously discussed, you will often have better results if you take a photo from further back, and crop, instead of using close up photography with Macro Settings.

Samsung Galaxy S2 HDR Photo Apps

After a week with my SGS2, I've decided to play around with filtering and photo techniques abit more. I've seen some great results with HDR photography and wanted to experiment myself. HDR or High Dynamic Range imaging, creates a greater range of luminance and contrast between shades of colour in photos. HDR photos can be achieved purely through the post processing of images, or through the combining of 3 or more photo shots with slightly different ranges into one. As the latter is the preferred option, i opted away from Android apps like the popular 'Camera 360' which uses post processing, and instead chose 'HDR Camera+' from the app market. Below are my first results. The first photo is without HDR, whereas the remaining 3 images are taken with 'HDR Camera+', whereby I've chosen 'High Contrast' in the 'Local Contrast' options of the settings menu. Click on each photo for a full resolution view.

Lessons learned:

As you can see, the results are dramatic. Though on reflection, i will probably opt for a subtler contrast next time, as the luminance is alittle overkill.

I'd also warn that unlike professional camera's with HDR features which take each individual SDR shot in rapid succession for combining, the 'HDR Camera+' app has approximately a .5 delay between each of the three shots, which means that unless you hold your camera incredibly still and use only static images, you will not have the same crispness to the images that you may wish for. I will research means to reduce this lapse, and test similar apps to see if this is a universal issue.
