Any Little League batter knows not to hold the bat that way. Surely a professional should know better:

Always keep the seal on the top, i.e., swing with the grain aligned with the direction of the swing -- unless you WANT the bat to break.

I've been saying for years that DSLRs should do this.

WGVanDyck: This is essentially a photo and image site and I find dark grey to black backgrounds work best for that type of content. One of the reasons I like DPR over that other site.

For me, it's just personal preference. White surrounding a photo looks clean, but the photo appears more washed out. Maybe it has something to do with aging eyes.

But seriously, thanks for giving us a choice. This way everybody will be happy. (Okay, not everybody, some people will always find something to complain about ...)

Personally I like the new light theme very much. Much easier on the eyes. Can't wait to have it on the forums! :)

The Kindle app for iPad has several settings for page color and text color. I prefer using a setting that's about 2/3 white, with dark, but not black text.

Dark background is good for photo-rich pages. Light background with dark text is better for the forums, in my opinion. I don't see the new white skin in the forums, however. I guess the preview does not extend there.

ZAnton: Tried it. Eyes hurt. Back to black.

Funny. The main reason I've been asking for white is that bright text on black hurts the eyes. With a white background, the eyes stop down to a comfortable level and I don't get burn-in. With black background, my eyes compensate for the black by opening up, with the result that the lines of text burn in to my retinas, leaving an afterimage.

You're right. I'm wasting my time by continuing in this thread that you persist in leaning toward ad hominem. I will agree with one thing: the readers surely can decide for themselves who has valid points. Reading list may include posts from other forums here and other sites.

Digidog, your comments indicate your ignorance.

That doesn't read very well, does it? I suggest you refrain from that sort of talk and instead just discuss the issue.

Getting back to the point being discussed, I think it's very well established that the Adobe profiles for the 5DS cameras is different. They've essentially admitted that (not that it's worse, but that it's different). This is not news.

The profiles are wrong because they are inconsistent when compared to Adobe profiles for other cameras. The main issue in the result is not the cameras but the profiles.

Part of what we hope to achieve with profiles is consistency. The 5DS profiles have destroyed whatever consistency there was.

Sure, I can make my own profiles, but I didn't have to before this camera model.

BTW, taking video or pictures at various times of day does not challenge my assertion.

The spectrum can change depending upon what is in the atmosphere filtering part of the spectrum selectively. Of course, in those situations, where the air is full of pollen (which can cause colorful halos) or dust, you may wish to use a standard daylight profile anyway precisely in order to capture the eerie effect produced by the unusual conditions.

I had a bush where these bees would perch like this every night. Amazing that chomping down on a twig is their most comfortable sleeping position.

On article Create your own DSLR external battery pack (65 comments in total)
In reply to:

gerard boulanger: Why buying/carrying that when you can put 2-3 extra batteries in your pocket?

The last time I did significant video, I had three CF cards and three batteries that got rotated together. We did have a handy AC outlet for charging the batteries. If we didn't, we still could have charged them using an inverter connected to a car's cigarette lighter.

CF capacity was 32 GB. We rarely got close to filling them up. We generally ran out of battery first - this using a 5D Mark II.

I can see this being useful if the shoot involves long clips. If, like in our situation, you're shooting mostly relatively short clips, rotating batteries and cards works just fine.

We actually rotated more frequently than we needed to, because this was part of a 48 Hours Film project, so we wanted to get files to the editor ASAP. I suppose we should have aded Card and Battery Runner to the credits. :)

If anyone follows the links for still use (because video is not available on the classic) on a Canon 5D, be aware it doesn't use the battery type linked under the title 5D. That battery pack is for 5D Mark II and Mark III. The 5D uses a different battery pack.

On article Get more accurate color with camera calibration (265 comments in total)
In reply to:

Charlie boots: This sounds more like lightroom calibration to match the camera than camera calibration as the calibration is only appliccable when using lightroom and is only appliccable to a specific light colour. Change the location and the light and one needs to recalibrate for the new light situation. This then means that for each photo shoot there needs to be a new calibration. How does one then manage within lightroom as it is not possible to automatically have lightroom change claibration profiles automatically to match each photo shoot. This has to be done manually.

The main point of accurate color is CONSISTENT color. Use it as a starting point to make your faux colors consistently relative to a standard.

Vamp898: After several tests i can summarize that you dont have any advantage using this on a Sigma SD1.

If i take a completely uncalibrated Test-photo of the Color Checker with the Sony a99 and the Sigma SD1, the Sigma already shows all colors correct where the a99 seems obviously to change the colors to somewhat liking i dont know.

So for the Sigma owners, you most likely dont have any advantage as you already have a good camera.

So the Sigma SD1 knows about all possible light sources? I doubt it.

In reply to:

WalPhoto: The information is partially incorrect - you can NOT create "a general" profile for all lightening situations combining the ICC profiles! This is not "my opinion", this is the fact color correction works. The ICC includes a mathematical matrix transformation from one color space (the concrete colors, how they came) to another color space (how they should have come). So, let's say you light a scene with a strong blueish light, e.g. flash, say with a blueish filter, to have the example even better understandable. Now you create the ICC: it will transform all the blue-cast colors to be more yellowish. This will DESTROY any image when applied to a total different lightening, say yellowish (candle light)! And interpolating those 2 extremes cancels their original reason for creation. I was running an ICC profiling service a few years ago, so I understand it a bit. Peace, Andrej

But you can create two different profiles, process the image separately with each, and then combine them in two layers as appropriate.
