Photo Forum / Digital Photography / DSLR Cameras / January 2005What format fo save NEF files from APE3
Thanks to this forum I am able to load NEF files from my Nikon D70 into Adobe Photohop Elements 3 and see the main adjustment screen with histograms and all the other goodies. I love the Digital Darkroom approach! Since APE3 can't save in NEF format, I have to choose between Photoshop, JPEG 2000, TIFF or PNG. There are also three photoshop formats: Regular, PDF and Raw. I was hirrified at the size of the regular photoshop format 25GB+, and decided to save in JPEG 200 25% quality. Is Phtotoshop RAW format better? Any recommendations? Thanks in advance/Anker I would save it in TIFF, or Adobe PSD. The reason is Adobe PSD preserves all your layers which you may want to edit at a later time and is an uncompressed format. JPEG is a compressed format, that loses information. This is how it saves smaller files.

If you want to advance your digital darkroom technique you need to learn about file formats, using Photoshop layers and color management. If you gag at 25mb images then there is no point in learning digital darkroom techniques. D70 images saved as tiff or psd format will be in the 18-50mb size depending on how many layers you create and what type of layers. The psd format is best as it preserves your working layers. If layers are used properly the original image is untouched at the bottom of the stack. You can also save the NEF or jpeg file as it came out of the camera with no further adjustments. It may be heresy but I believe beginners are best served by using the fine jpeg settings in the camera and learning to use Photoshop on them before working with raw files. I presume you have a CD burner on your computer: you can off-load images and restore room on your hard drive. Epson has an online course that is a very good introduction to Photoshop, layers and color management with video presentations of how things are done. >Thanks to this forum I am able to load NEF files from my Nikon D70 >into Adobe Photohop Elements 3 and see the main adjustment screen with >histograms and all the other goodies.

You can't overwrite camera RAW files in any app afaik, this is the raw data from the sensor with added algorythms for white balance sharpness and other paremeters depending on your camera and/or raw converter. If you make changes in the Elements 3 converter these will stick to the NEF file if it is subsequently opened in Elements again, I think, it does in PS CS. For saving to a readable image file format my choice would be TIFF since it's the most universal of the three you stated and can be read by most image applications. Using PSD will preserve certain PS/Elements proprietary features such as layers.

Nikon Editor as part of Nikon View will allow this as well as Picture Project also supplied with certain Nikon cameras. I've been bit by this at least once and had to use recovery software on the CF card to get the original back. ________________________________________________________ Ed Ruf Lifetime AMA# 344007 (Usenet@EdwardG.Ruf.com) See images taken with my CP-990/5700 & D70 at http://edwardgruf.com/Digital_Photography/General/index.html Thanks for all the input. The tradeoffs are so significant that it looks to me like I need to decide on a shot-by-shot basis whether I am taking a snapshot or a carefully planned photograph that I intend to optimize. For snapshots I'll use P, S, M, or A modes with Normal, Large JPEG processing in the camera, and for "real" photography I'll use P, S, M, or A in RAW mode and copy with the large NEF and PSD files. I fortunately have a 320 GB partition and will back up to DVDs. I plan to avoid Auto and the rest of the modes. I really hate the camera deciding whether to use flash or not. Thanks again/Anker >I plan to avoid Auto and the rest of the modes. I really hate the >camera deciding whether to use flash or not. Worse than that, Auto applies a whole bunch of image dependent adjustments, brightness, contrast, saturation, sharpening, etc. So you have no idea what to expect. ________________________________________________________ Ed Ruf Lifetime AMA# 344007 (Usenet@EdwardG.Ruf.com) See images taken with my CP-990/5700 & D70 at http://edwardgruf.com/Digital_Photography/General/index.html >Oh don't be so sure about that.

What the Nikon software does when working on NEF files is save an instruction set, or a set of commands for the file. It doesn't actually change the NEF itself. >>Oh don't be so sure about that.

How do I get back to the original full image? ________________________________________________________ Ed Ruf Lifetime AMA# 344007 (Usenet@EdwardG.Ruf.com) See images taken with my CP-990/5700 & D70 at http://edwardgruf.com/Digital_Photography/General/index.html >>You can't overwrite camera RAW files in any app afaik, > >Oh don't be so sure about that.

You're not overwriting the RAW sensor data only the intructions for importing, these can be non destructively changed after the fact but the actual data remains the same.
