Photography Technique / Re: Long exposure on an unstable platform
« Last post by RChauhan on Today at 12:29:15 AM »
Sure it would be nice if the containers could be a little sharper and you might be able to figure a way to achieve that, possibly by mounting the camera to some surface iof the ship and using IS

A 20,000 HP engine on a seagoing vessel makes a fair bit of vibration, and you also get flex over the vessel. hard mounting the camera to the ship makes it worse.... we ended up using mounts that clamped onto a post and a 2" thick rubber plate to cut down on vibration.

Try 50,000+ HP  ;D
we had 150,000HP.... but the 20,000HP diesel made far more vibrations that the pair of 55,000HP turbines....

Sounds like a Dynamic Positioning Dive Support or Offshore vessel? One main engine and the Turbines when on station? I work on large merchant vessels so totally different scene. One massive engine. One used 170 tons of heavy fuel a day.

Yeah, turbines are much smoother. I once heard Diesel engines described as the best way to turn fuel into noise  ;D

Software & Accessories / Re: Magic Lantern Running on EOS 70D
« Last post by Tiderace on Today at 12:27:33 AM »
I have an early Canon 70D and apparently Magic Lantern states there method does not work with this early models firmware.  They state that Canon used a substandard firmware that is inadequate and should never have been used.   They say Canon should offer a fix. 

Please help canon.  I cannot use Magic Lantern. But more importantly is my firmware not adequate.

Hi all,

Thanks for the suggestions and discussion. Here are a couple of comparison shots (unprocessed, just exported from LR as JPG):

Maybe not the most dramatic example, but these are two relatively good side-by-side comparisons.

Happy to hear any thoughts on what's going on here -- problem with my technique, expectations too high, etc.

Thanks,

Ok so what are we looking for here? The heron shots are under completely different light and the killdeer shots look pretty similar.

A crop camera  does not magnify defects, it crops the center of the image, and you generally get fewer issues which generally show up on the edges of the image circle.

Sure, but what flaws there are will be magnified more the smaller the sensor is, for a constant view or print size.

Very nice images for a manual setup!!  You might consider having a play with gelling the flashes, different backgrounds, and different liquids (milk, water with glycerol/corn syrup dissolved in it to increase viscosity, etc.).

If you're interested in 'throwing money at the problem', there's the Cognysis StopShot...

What about soap to give it a rainbow color?

Sorry everyone - You don't need a faster shutter on a 7D over a 5D in fact if anything you could get away with a slower shutter since the frame will contain fewer pixels.

On the other hand, if you are not comphensating for framing, you will need a 55% faster shutter (61% faster from the crop / 1.1 slower from the decreased sensor density) at matching focal lengths if you want to see increased detail that would otherwise be lost to motion.  At a given shuter, you  are NOT going to lose detail on small subjects, you only increase the chance of having motion blur which will be the same amount as the 5D only zoomed back by a factor of 1.6  In other words the image will NOT be worse, it will be equal or better on content already being cropped.

Having cleared that up; the differences you are seeing are probably due to lens quality.

If you were to say that Full frame uses 100% of an EF lens, you could say that crop uses only 39% of that.

This magnifies the defects.

The better the lens, the less of an issue.

Hope that makes sense.

Even Canon recommends a faster shutter speed for crop cameras using the same lens at the same distance.  Image blur happens due to motion of the camera during a photo.  The smaller and closer photosites mean that a slight movement will blur across the pixels.  If you compare a crop camera with a FF body having the same pixel size and spacing, that would not be a issue.

A crop camera  does not magnify defects, it crops the center of the image, and you generally get fewer issues which generally show up on the edges of the image circle.

Photography Technique / Re: ball on the bat... frustration leads to cheating....
« Last post by jdramirez on April 24, 2015, 11:57:12 PM »
I usually focus on the ball with the intention of hitting the shutter before the ball enters the strike zone... I get several non shots... just people standing looking at the ball... but that hasn't been that effective.

How does left-handed verses right handed batters work for you?  1 out of 100 isn't that bad - those are odds most folks would take any day.  PhotoMechanic to quickly remove the shots that weren't just perfect.

Our team is entirely comprised of right handed batters... so that makes it easier for me.  But when I'm on the wrong side of the field... I usually just wait for the follow through... which can be dramatic in and of itself...

The new 100-400?  It's only a whiff heavier than your 70-200.
