Heh – I had been so good lately about planning ahead and recording my video podcasts ahead of schedule and just setting a publish time in WordPress, I got on an automatic pilot routine. When that routine got disrupted from some dental and sleep deprivation issues the other day, I didn’t realize until just a short time ago that the post for Friday had not been scheduled. Not only had it not been scheduled – it didn’t even get written yet!
So, a thousand pardons as I rush to get a somewhat photo-related post out before the end of the day. Since it is on short notice, I will simply relay a funny story that happened to me the other day as I was out walking the dog. I had taken the camera and flash with diffuser attached as the day was actually perfect for photography: late afternon, cloudy skies, and evenly light all around. So, I am bouncing along, trying different settings here and there with various subjects – a flower, a reflection in some water, and I have the bright idea to do a macro shot super close on a flower. But, instead of going wide open to get available light, I figured let’s try the flash here – so I pop the flash on, attach the diffuser and set it to ETTL. Then I dial the aperture down as far as I think it can go on the fill flash setting – f22! I pre-focused on the lower third of the frame, then set the focus to manual. Finally, I shifted the camera up just a smidge, knowing that the lower portion would be in focus and because of the f-stop, I would have a pretty solid dof throughout.
Well…there’s always something you forget, and in this instance, it was the ISO setting. You guessed it – 1600! ARGH! Well, I cleaned it up a little with NN after the fact, and yeah, it’s okay, but imagine how this shot would have been without the noise and tack sharp?
So, it seems another one that got away from me! I think I am going to tape a label to the back of my LCD and write on it in big fat letters ISO! Long story short – always double check your settings, and always take a few shots. I only took the one, so it’s all I had to work from. Oh well…better luck next time! Hee’s your traditional WTD episode for Friday:
Hope everyone has a good weekend. Happy shooting and watch those apertures!
Bop bop doo bop doo bop do wow! Okay, sorry, that’s a bad skit for the great jazz tune from the ’50’s, but nevertheless, whenever I hear the phrase “in the news” I feel compelled to sing that line. Now, for your real news from CB today: I’ve got two stories for you, some news from Adobe on the next iteration of Photoshop and some Canon news on the Canon Hacking Development Kit (aka CHDK) that is now maing waves. Read on for all the details!
Adobe Photoshop News
Well, the big news I read today during lunch was that the folks at Adobe will be incorporating some sort of GPU support for its next iteration of Photoshop. Tapping into the GPU (graphics processing unit) means that larger images can be rendered on your display faster. Another added benefit will be an increase in processing speeds for filters and other intensive activities. Nothing too earth-shattering, except they did report that at the Nvidia show, they watched the presenter zoom and rotate the canvas on a 2 GB image as though it were a 5 MB image.
Canon CHDK News
In more Canon-specific news, I have now read at least 10 articles from a number of resources talking about the Canon Hacking Development Kit (CHDK), which is a free firmware hack that can be applied to P&S grade cameras to allow them to do a number of things that SLRâ€™s do, and even a few that your average SLR canâ€™t do!
- The CHDK allows Point-n-Shooters to shoot in raw mode. The caveat is that since itâ€™s not a standard raw format, you canâ€™t open this in Photoshop or Lightroom directly. Instead, there is a third party software kit out there (also for free) called dng4ps2 that can convert the image to the more common DNG, which is Adobeâ€™s Digital Negative format. The DNG file can then be opened in Photoshop or Lightroom.
- The CHDK kit enhances the P&S feature set by adding a battery status indicator so you can see how much of a charge you have left on your battery. I know this feature is already there in SLR cameras, so I guess the P&Sâ€™er didnâ€™t have this feature regularly â€“ news to me.
- The CHDK kit also adds what theyâ€™re calling a zebra mode which will show you whether a picture is under- or over-exposed. Basically, it sounds like itâ€™s adding a histogram feature. Again, this feature is standard on most SLRâ€™s, but not on most P&S cameras. I just think that even a lot of SLR shooters donâ€™t use the histogram (although I would personally encourage more use of it), so adding the feature on P&S cameras may be a little overkill.
- Finally, the CHDK kit allows P&Sâ€™ers to extend their range of shutter speeds. The most reliable info I saw for the CHDK claimed the range went from a standard of 1/3200-15 seconds all the way up to a range of 1/33,333 to 65 seconds! You read that right, thatâ€™s one-thirty-three-thousandsth of a second (and change). Kind of makes the 1/8000ths shutter speed on the 40D look pathetic, eh? Granted, this was specific to the S5 IS, but the standard change is to 1/64000ths of a second, which is still earth-shatteringly fast!
Now, the caveats:
- Write time slows down considerably when shooting in raw (to about 2-4 seconds â€“ yikes!).
- The raw file format is not recognized by mainstream applications like Photoshop and Lightroom. In other words, file accessibility is likely not reliable.
- The software that you have to use to access the raw image data is freeware. While some software from the open-sourced community is excellent (case in point GIMP, OpenOffice, and many others) and perfectly safe, the fact that this software comes from Russia and is (to my knowledge) untested, sets off red flags all over the place for me. Of course I work in IT, so itâ€™s in my nature to be suspicious of third party software from third world countriesâ€¦
- As with any firmware hack, this is likely going to void any manufacturer warranty or vendor support for the camera if you install the software.
So, having shown the pros and cons, Iâ€™ll leave it to the community â€“ install at your own discretion. For those that do decide to install, feel free to share your thoughts here in the comments, or with me via email â€“ Iâ€™d like to hear feedback on the reliability of the kit. The CHDK can be downloaded direct from the link here: http://chdk.wikia.com/wiki/S5IS, and the raw converter from here: http://dng4ps2.chat.ru/index_en.html Until next time, happy shooting and watch those apertures (or should I say shutters?)!
After I recorded and started production on this tutorial my mind began to remember that perhaps I had covered this subject before. I reviewed the subjects I have posted over at the Tutorial Resource Center and did not see it covered there, so figure I am not repeating some tutorial I have already done. Having said that, this is kind of a return to the basics. Read more
