This is a very basic tutorial, requested by some friends who are new to raw file conversion. For more advanced discussions, you may read Part II and Part III.
In this part, I am going to discus how to get around the first and the geceral tap of the raw interface and what all those buttons mean. To convert a raw file, do the simple things first and follow the instruction below. This will already give you a big start on improving your capture, getting your WB right and set your exposure correctly. Open the attached image and look at the interface: 1- Open a raw file in PS (file/open/any raw file) #1 is your color space, leave it at Adobe RGB. #2 is the zoom level of the opened file. It always opens at this level so that you can see the whole file. #3 is the color depth of the file. Leave that at 8 for an average file but you may want to change it to 16 if you have a special file that is important to you and specially if you want to do a lot of post processing. Bit level of 16 will keep the color integrity better through processing and it also helps in high quality printing. But, using level 16, will make your file twice as heavy. So, use it when you need it. #$, #5- leave them as you find them. #6 is your zoom tool and #7, the hand, will pan your image when zoomed. #8 if checked, will turn your highlights to red, if blown and #9 if checked, will turn your shadows to blue if clipped( clipped shadow is shadow that will not be recoverable in Post process) #10 is your WB, very simple. Turn it up and your colors will look warmer, turn it down and they will look colder. #11 is part of the WB and you can forget about it for now and leave it as you found it.When your eye gets keener, you may tackle this. #12 is your exposure, VERY simple again. turn it up and you'll expose more. You may turn it up until you get a highlight warning(red highlights if #8 is checked) You may want to leave # 13 as you found it for now. #14, brightness is basically your mid tones. You may want to play with it or leave it as you found it. If turned up, you'll get a lighter image and if turned down, your mid tones will be darker and maybe richer. #15 is pretty obvious and click on #16 when done. After clicking on Save, If you want a JEPG file, the new window should look like the second image I will insert. If you want to save in Tif format, then chose Tif where it asks you for file extension. Again, use JEPG for an average file or chose Tif for a more important file. A tiff file is uncompressed and is many time heavier than a JPEG but it will not disintegrate if opened and closed many time, A Jpeg file will!! This is the first page of the raw converter interface and you can REALLY get by only being concerned with this page for now. Cyrus
