Аs I mentioned before, in my previus blog RAW format is it a Plus or just a waste of digital space? most of the time i use RAW + JPEG mainly to check if the composition is right, the light is correct overexposed/underexposed areas and other minute changes in the photo.
And then when I had a little bit more time I used RAW for the post-processing:
Even do the end result was a JPEG image, there are some small diferences and the reachnes of detail remains in the images that ware made from the RAW format. This is due to the nature of the RAW format and the way it captures the image.
If you shoot in the studio you are probably already using some system for fast transfer (wired or wireless) your shots to the PC or MAC directly to a software that can process both JPEG or RAW or both formats at the same time. One more reason for me to use RAW and JPEG at the same time is because I use Adobe© Bridge® most of the time when I make selection and ménage my photos. In Bridge® I usually line up my photos in my right side thumbnail bar, both formats side by side so you can instantly see the differences in your image, this contributes to the fast workflow process and you right away know what you RAW image needs improving and in which direction.
One more added comfort is that if you go for the described HDR process or the photo-stitching process (in my previous blog) you already have one JPEG to start with and only need to create from RAW just a couple more to merge them in Photoshop® or any other program to create HDR image. If you need to produce a large panorama or other composite image for faster workflow and lesser CPU and RAM exploitation use JPEG's for faster results (and in most of the time JPEG's will be enough for a final result).
I hope this will be enough convincing for anyone at least to think when to shoot just RAW and when both RAW + JPEG.
