Soft means undersharpened, as what was stated. If you go into Photoshop or whatever your post processing software is, increase the percentage and radius. If you have an option to eliminate blur, use it. Here's an example..



good luck next time!

Hi Matt,

When they say "soft" it can mean undersharpened, or it can mean that the image itself has a soft focus......for whatever reason, the lens was not sharply focused, or the shutter speed was too slow.

Usually, this is most noticeable in text (numbers/letters) on the lead locomotive. Your original shot does look soft to my eyes, but I have no way to know whether it was an execution issue or a postprocessing thing.

Shutter speed of 1/160th, according to the exif data, so it might be difficult to get the train sharp. Nice composition, give it a little sharpening and see what happens.

Keep it above 1/250 s, next time! I try to stick around at least 1/400 s, if I can help it.

Compare your rejection to the fix that Carlos did. Put each image in a different tab and go back and forth. The difference will be obvious to you.

You go down that to 1/400th? That would have me worried especially on a train moving. It can work but you're taking a risk.

I would say try to get to at least 1/640th, 1/800th or 1/1000th. If the camera your using is anything within the past 10 years, ISO 200 should not be a problem for it. Set at f7.1 or so and you should have a well exposed and well sharpened shot.

I remember when I first got a DSLR and didn't realize how fast of shutter speed it took to slow an 80mph train. Unfortunately I butchered a few nice shots before I started cranking up the speed.

Well, it depends what I'm shooting! A freight doing 30 mph is OK at 1/400. Of course I use a faster speed for a highballin' VIA doing 100 mph.

I remember looking at the shutter speed of some of Jean-Marc Frybourg's TGV shots and they were slower than 1/1000 s, so...

This one for instance was shot at 1/640 s!
