I decided I’d like to write an occasional photography how-to post. Well into year 2 of Project365 it’s obvious I enjoy photography and it seems that some of my readers do as well, so why not?
I’ll tell you one of the secrets to my photos – post-processing.
What that means is that what you see is not necessarily how it came out of the camera. I used to be a bit of a purist, that I had to get the settings exactly right and the only thing I did before publishing was to resize and apply a watermark.
Probably a year ago I became a convert to shooting in RAW mode instead of JPG mode. What’s the difference? This graphic that I found on PetaPixel explains it well (and was the inspiration for this post!)
All those things on the right that the camera does? For the most part, none of those actions can be undone. SOME editing of JPGs is possible, but no where near the editing that can be done on a RAW file.
- photo was under- or over-exposed?
- white balance settings were incorrect?
- saturation isn’t to your liking?
- should have used a flash for some fill light?
- want to try some ‘artistic’ editing of your images?
These issues and more can be fixed by editing the RAW file, even better use Lightroom and you’re making non-destructive edits, that is the original file from the camera is unchanged, you’re basically editing a copy, making it easy to go back.
So just what is a RAW file? I think of it this way- my Nikon D90 has a 12.1 megapixel sensor. The RAW file contains the original data (for the most part) from every one of those pixels, which is why the resulting RAW file is ~12 megabytes in size. Every pixel is available for editing, in theory, no data has been lost.
There are some downsides
- large image files, takes a lot of disk space (unless you delete ruthlessly, which I’ll write about one of these days)
- post-processing software is necessary. Nikon has their own program which I think is free, though most people use Photoshop, Photoshop Lightroom, or Adobe Aperture.
- time, probably 50-75% of the photos I post have at least a little processing done, which takes time.
- burst-mode speed is reduced. My D90 can shoot at 4.5 frames per second in burst mode when saving to JPG, which is great for action shots and stuff with the kids. Set to RAW mode and that speed goes waaaay down, due to the large file size and data transfer speed limitations of the processor and the memory card.
Can’t decide which might be for you? Shoot in both RAW and JPG! Most cameras have a setting where both RAW and JPG versions are saved for each image. I did that for a while and unless burst speed is an issue, I’ve switched to always shooting in RAW.

Confused by any terms?
Have a suggestion for another photography post?
Have other photography technique questions?
Thinking about buying a new camera or lens?
I don’t know where this is going, and I’m certainly not a pro, but I enjoy sharing my experiences and knowledge, so don’t be shy, use the comments to chime in with your thoughts, ask questions, tell me I suck and shouldn’t be doing this, whatever comes to mind.
Have a great Sunday!
























Memory
I came across this on PetaPixal the other day and it reminded me of a conversation I had with Darling Boy over the weekend. He made a comment about how big computers used to be and yet how basic they were- “Hey dad, did you know that supercomputers used to be the size of our house?” I love when he tells me things he thinks I’ve never heard before, so of course I play along and acted surprised. I don’t want him to think I know everything (hahaha yeah right…), though I did point out that my iPhone probably has more computing power than the systems NASA used for the Apollo moon landing missions, which made his little head spin
Anyway, here’s the tidbit I saw-
YEAR — Price of a Gigabyte
1981 — $300,000
1987 — $50,000
1990 — $10,000
1994 — $1000
1997 — $100
2000 — $10
2004 — $1
2010 — $0.10
Check out this ad, a whopping 11MB of hard disk space AND 64KB of RAM for the low low price of under $10K, what a bargain! Right know there’s an 8GB memory card in my DSLR, I think I paid about $50 and the individual RAW files from my camera are about 11MB each. I also have a 1TB external hard drive to back up all of my files, I think I paid about $120 for that. Digital photography, had it existed in the early ’80s, would have been pretty damn expensive!
========================================
Thanks to everyone who took the time to comment or e-mail me privately on yesterday’s post about getting caught, you’ve given me a lot to think about, which is why I haven’t responded to anyone yet. Katie is away on a family vacation this week and I’m traveling all of next week for work, I think there’s going to be a rather serious “what are we doing” talk when I see her again in 2 weeks.
