Bad Cropping Advice
 
Got bad cropping on these two images. Can they be fixed?

You had some nice lighting to work with, so I don't know why you thought 1/60th was sufficient enough to stop a moving train. The first one is too blurry on the nose, and the second one you have a bit of grass and whatnot in the way of the loco. "Better" cropping won't save either one of these, unfortunately.

Alright thanks Jim. What do you think would be a good shutter speed would be for a train around 80mph?

Dennis A. Livesey 01-19-2010 05:24 AM

Put me down for bad cropping advice!:p

May I suggest you look at this post?

My quickie wisdom:

1 Sun behind your back.
2 Camera in Manual.
3 Low ISO like 200, shutter 500 or 1000 to get the locomotive sharp.
4 Pick your focus point where the loco will be.
5 Composition: Off Center is Better!

Well, I think you'd be better starting out with a wider aperture. You shot that a f10. f5.6 would have enabled you to shoot closer to 1/250th. However, that may not have been fast enough either, so bumping the ISO up from 100 to 200 would have allowed you to shoot at 1/500. So, f5.6, 1/500th and ISO 200 would have given you a similar exposure and froze the train.

A few other things to keep in mind next time you're out:
- Make sure you can see the head of the rails without anything in the way (such as grass)
- Do what you can to manage the placement of trackside telephone poles (so they don't look like they're sticking out of the top of the train).
- Remember that you're having fun and learning something, even if the shots don't get accepted right away. Keep at it, keep a positive attitude, and you'll be shooting better quality photos in no time.

No trackside telephone poles for me. :)

I just noticed it, but based on the title of this thread, what is good cropping advice?

As Jim said, you had good light, but unfortunately, you messed up on the settings and the foreground clutter, thus, I personally find, making it hard for these photos to make it in the DB. I'll add to what others have said.

An 80MPH train will need a decent shutter speed to freeze the train, regardless of your angle. A telephoto photo, or the simple "wedge" will require something above 1/250" at F7.1 with an ISO of 100. For safety, you may wish to either decrease the aperture to F5.6 or perhaps increase the ISO from 100 to 200, that way you can reassure yourself that you'll have a "crisp" photo. The following was done at 1/320"..

[photoid=301830]

This one was done at 1/250"..

[photoid=300876]

I would've preferred to have done a faster shutter speed on the above photo, but thankfully, it still turned out decent.

An angle like the one below, required a faster shutter speed in attempt to freeze the train, due to a slightly different angle than the above photos. This angle, which shows off a bit more of the side of the train, is also known for increasing your chances of blur, especially for a fast moving train, such as Amtrak. Thus, with that being said, I increase it to 1/640" to prevent as much blur as possible.

[photoid=270589]

Hope this helps,
Chase

Quick and effective, Dennis! I like it! :)

Thanks everyone! I'm still getting use to my new DSLR. Just got it a couple weeks ago. I will learn from this and hopefully get it right next time. Once again I value all of your advice/feedback. Thanks -JT

Are you using manual settings?

Well, he said he wanted bad cropping advice. Therefore, center your subjects, cut off plows and the end of trains.

:D

What does this have to do with cropping? ;-)

PS : Nothing, btw.

Ben,

Not sure if you've been following the thread or not, but the blurry locomotive on the first image is the main problem over the cropping. It was a 1/60th exposure, which could've been a result of using auto settings, hence my question.

It was a pretty valid question by Chase considering we (Chase and I) were discussing camera settings with the OP due to his blurry shot. Just sayin'.

Joe the Photog 01-20-2010 02:10 PM

Jim, Dennis and Nick all made comments outside the realm of cropping -- and I would have if the issues hadn't been touched on before I found the thread -- yet Ben only brought up Chase's question. Interesting.

asis80 01-20-2010 04:19 PM

Hoooooooooooooooooooooooooly cow guys. REALLY didn't mean it to sound harsh, haha. I was just joking with you Chase. Haha, really was.

I was told that 1/640th was a good starting point. Granted, this isn't necessary when shooting a 10mph train and posting the shot strictly on the internet, but I myself wouldn't go slower than 1/640th if I were shooting a 60 mph train.

I use 1/640th f 7.1 as a start for straight sun, and go from there with what the light meter wants to do... If I'm in high speed train territory (60MPH+) I'll even jump the ISO to 200 to stop it.

Gosh, "even jump the ISO to 200" - what a drastic measure! :)

People are too concerned about noise sometimes, me thinks. I shoot ISO 400 frequently and I've got an old 20D.

So then you bump up the shutter speed to 1/1250, right? ;-)

Unless you're shooting super wide, or along the Northeast Corridor, there's really no need to shoot above 1/500.

I sometimes have to shoot over 1/500 to stop the Shays. ;-)
