Default Bad Contrast

Hi. I'm relatively new to DSLRs and image processing. This picture

http://www.railpictures.net/viewreje...d=443394&key=0

was rejected for "Bad Contrast: The image suffers from either too much or too little contrast."

I presume (?) it doesn't have enough contrast. Do you think it can be saved by increasing both brightness and contrast? I'm using the Canon "Digital Photo Professional" software that came with my camera.

Any advise or suggestions appreciated. Thanks.

Doesn't look like it's hopeless, so you certainly have a chance of improving it with photoshop (or someone else for you). But with acceptable contrast, it MAY get rejected for "poor cropping" or "poor balance" due to the center placement of the subject. There also seems to be some grain or image quality issues, as evident by the image noise on the lower (darker) part of the engine.

Definitely more contrast, doesn't look like there is any black in the picture, only dark gray. I agree with Jim on the cropping, perhaps try a vertical composition, removing lots from the right side.

I tried playing with it a little bit...since its not the original file, I can only do so much.

Where is the original file? The first step in learning post processing is knowing to never ever write over your original copy. Save with a new file name as the biggest, most resolute image possible and work from there.

Also, just to note, the image you attached is only 191K, much too small to work from and even to upload.

I took the image through Adobe PS Elements and could not fix the contrast issue. I don't know if working from the original will help in this case. (Which is not why you should save the original as working from a copy this small will almost NEVER work.)

Wow! Thanks for the great feedback.

I played with the contrast and brightness and improved it a lot. I also tried cropping out a lot of the stuff on the right side per your recommendations, but I felt the resulting image of the loco was too soft and I couldn't fix that well enough. (The train was small and relatively far away in the original image and the cropping made it large enough that it became too soft.)

So, I selected another picture later in the series of images I took--one where the loco is much closer and dominates the skyline, rather than the other way around--and I've submitted that one. We'll see how it goes. Great learning process.

Thanks again to all. I appreciate the assistance.

P.S. I do have the original image. It's over 4MB in size. I never save over the original (or at least not intentionally).

Hey, astro;

What was the verdict of the next one you submitted? Just curious. Glad to hear you weren't writing over the original image. I couldn't tell if that is what you had done from your post or not.
