Un-retouched photos - Galleries
It is my understanding that in any digital cameras, image processing
is made inside the camera using the image sensor processing engine. In some advanced digital cameras, they let the users keep the unprocessed photos (RAW files), instead of the JPG files (which had been processed by the camera). My questions are as follows: - what is the extension file for RAW ? (like .jpg in jpeg files) Could this RAW files be viewed using any photo viewer software (as they are, i.e. without interference or retouching from the software?) . Or everytime you open the RAW files in a certain viewer (like picasa, PSP, PS, etc), it is automatically semi-processed by the software before they are shwon on the screen. - Do all or most available photo galleries in the websites contain photos which have been modified or re-touched? How do you identify gallery sites which contain photos that are NOT retouched? Are there such websites which only promote unretouched photos? If I want to see how the various cameras compare in producing its pictures, I consider the "inside" processing by the camera for the first time is considered as original pictures (one chance for the camera's processing engine to form the picture). However, I heard that some cameras now allow for re-touching while viewing in the camera. It is another manipulation addition, and I would not considered the manipulated photos as original. I would be interested to know if there is a way to find out that a JPEG file has been re-touched by a software (PSP, PS, etc), or even if it has been retouched inside the camera. Is there a way to find out? I saw incredible portraiture photos in a number of the photo sharing websites, and they have colourful, sharp photos. The ones that I particularly like appeared to be taken using a D2X, D70 or D200. My question is again, whether any manipulations are done on the photos. Could someone show me similar kind of portraiture photos taken using other brand name pro cameras (i.e. with similar rich colour and razor sharp images)? On similar line of thought, I also saw photos which are presented by camera reviewer websites - photos taken out of the box as part of the review of the camera. I assume these photos are nor manipulated (other than done inside the camera). Unfortunately, I can see that NONE have good, rich colour and sharpness that I like. Someone suggested that it is perhaps my computer monitor that needs adjustment. But, I am seeing the photos on the same computer. There are a contrasting difference between these photos and the one I saw at photo galleries. Thanks for info and discussion. |

I use a Nikon DSLR and the RAW file it produces use the extension .nef which stands for Nikon Electronic Image File. Generally RAW files such as Nikon's NEF files are edited in RAW conversion software, then saved and stored as digital negatives, after which they are converted to tiff or jpeg files for additional editing, saving, storage, printing or viewing. RAW files are 4 or 5 times larger than jpeg files so viewing them in viewing software, if possible, would be a slow going process. For electronic viewing they should be converted to jpeg. |

Interesting but there is another question have you calibrated your display?
a few video cards are supplied with software and a colour comparison card in order to get a true display of the image which allows even different monitors to show a true colour image. Happy as I am with the display in front of me I am positive that in some respects it fails to show images truly so some images I may percieve to be perfect in fact may be saturated bleached or have a colour shift. Don't get me started on Wysiwyg printing though. Derek |
