RAW is WAR!!!
RAW is WAR!!!
You'll Never Walk Alone! - i have the best job in the world!
my school teacher teach us to shoot in jpeg... easier to use leh.
Thanks for the clarification. Ok, now it all makes sense. Because the camera automatically did something to the image before converting to JPEG (like white balance etc.) and JPEG being lossy, some of the things may not turn out the way we like. So I guess the main reason to shoot RAW is to have a better control on how you want to edit it later. Am I making sense? Do I understand it correctly?
RAW most of the time unless its a event then its usually jpg.
Raw is the way to go!
Oh..another bad thing about jpeg though not always apparent or commonly known but worth noting. Overtime, (bad photographic skill aside) a jpg photo quality will also get less sharp, lose contrast, has weird colour bits..etc. You can see pixelation and weird pixels along constrasting lines especially. MOre apparent when you enlarge them for prints. This is because each time you open the jpeg file and make changes to it OR NOT...just by RESAVING the same jpeg each time... each time your graphic program will recompress the jpeg AGAIN. ..so the more time you open and save and open and save ..you are literally deterioting the image quality. It will start to gets more and more apparent as you use more higer compression on it to get the file smaller. So if you have open a picture and have not made any changes to it...don't try to save it. Just close the file and say no to resaving it. If you are shooting like 10 or 12mp photos...it is harder to spot it but when you are say using smaller size as in the sizes you use in website..the more time you work on that photo and doing numerous savings...you are in fact "aging" that picture. Yes most of us who do design work, we are always clicking the "save" button in case the system crash and we lose all the work flow done to a particular picture. So we don't work with jpeg. We open the jpg and resave a working version of it as tiff or psd.
A TIF or PSD file is not the same as jpg formats. A 18mb file (tiff or psd) saves as a 18mb file STAYS an 18mb file. Nothing taken out or compressed to make the file smaller thus the quality remains the same. The only thing bad that can happen to it is if you are lousy at photoshop and screw it up heheheh... okie....just abit more useless info about jpg format and why some folks rather shoot RAW. heheheheh

But 1 question here.
Why everytime I transfer my picture to photoshop from "Digital Photo Professional" , after editing, when I click on "save as" in photoshop, there is no JPEG format in the drop down list?
I'm using Photoshop CS 2 btw.
But my old files can be save in JPEG. Weird.....
There could be one reason for this. When you tranfser your RAW photo in Photoshop. The raw file's format will be temporary label as PSD. When you attempt to edit it and then save it or even try to perform certain colour adjustment...etc Photoshop will not allow it and some of those edit options will be disabled.
In the case of saving it as jpeg..if the photo is 16 bits channel you will not be able to save it to jpeg. You need to change it to 8bits channel. Go to the menu bar...select Image and go to MODE and you will see 8 bits/16bits/32 bits...just select 8 bits. Jpeg is a lower quality format so 16bit channel is too high for it so it is expect you should only save it in 8 bits channel. Once you have done so, you will now see more file formats now available in the drop down list at the SAVE AS prompt window.
Well I hope that is why you have this problem lah .

Also I believe certain colour modes aren't for JPG as well..
I feel that anyone who if he/she intend to get more serious with photography, should spend abit more time to learn about photo file formats, their limitations and basic editing with a graphic software. It will help them alot..it is part and parcel of photography in the modern day just like in the old days with film based photography where some knowledge about types of films, filters, processing ..etc comes into play.
The sooner one gets familiar with this the less problem you face. Nothing worst then shooting something very nice and while handling the file in your PC..something happens and bang!...bye bye photo. It does not happen often but when it does and with the most important photo. It really can sux your day's fun man heheh.
Shoot Jpeg in the beginning..... now RAW all the way....

Thanks for the write up. Sure clears the air about JPEG. I guess for final file for display on the web it is a good format. But intermediate format should be RAW. Thanks again.
