This is one of the most ground breaking applications and should really be useful for the mobile photography enthusiasts. Mobile phone cameras have improved a lot over time and have come to place where they are sucessfully challenging the domination of dedicated ditigal cameras. However the purists have always had a gripe over the processing algorithms used by the manufactures. Be in noise reduction, sharpening, colour correction there has always been something that could have been done better. Well, here’s your chance. Tea Vui Huang has just created a java based application that allows us to take RAW images in the DNG format which can later be processed to your liking.
4 years in the waiting, Digital Negative (DNG) – first introduced by Adobe in 2004 as a universal format for the RAW image files generated by digital cameras. Previously, cameras that provide direct DNG support are only available on high-end models from camera manufacturers like Hasselblad, Leica, Pentax (K10D), Ricoh, and Samsung. But now, with Tea Vui Huang’s free DNG Phone Camera, you can capture photos directly in the DNG RAW image format from your humble Nokia camera phone.
The DNG images will be saved to the “Images” folder of the microSD card using the default Nokia image file naming format. DNG is supported by Adobe Photoshop CS2, Photoshop CS, Photoshop Elements 3.0/4.0 and DNG Converter software. DNG raw files must first be processed before it can be used to generate a final JPEG or TIFF image.
DNG Phone Camera is designed for Nokia phones minimally supporting CLDC 1.0, MIDP 2.0, JSR 135 (Mobile Media) and JSR 75. This product includes DNG technology under license by Adobe Systems Incorporated. This should therefore work with most recent Nokia phones with the 240 x 320 resolution (Nseries and Eseries devices included). Here is a sample DNG image. For more info on DNG, visit the Adobe DNG website.
Since the program is in java there are a few customary permissions needed to be given everytime you take a picture, however it isn’t very cumbersome. But there is one more thing, the resolution at which it takes pictures is 640 x 480, at least for now.
What is the RAW Format?
A raw image file contains minimally processed data from the image sensor of a digital camera or image scanner. Raw files are so named because they are not yet processed and ready to be used with a bitmap graphics editor or printed. In short words, a RAW image is the result of the first impression the light sets on the camera’s sensor, without altering it in any way, so you can adjust all the variables freely (color, light, saturation, contrast, noise, sharpness etc).
You will not see any JPEG/JPG file on your memory card, but a DNG one, so before using the RAW image, you must “develop” it, with the help of some imaging software, like Adobe Photoshop and ACDSee, and after that save it in JPG format.
