Default What am I doing wrong?

I have 2 shots here that both got rejected for underexposure

http://www.railpictures.net/viewreje...&key=283487651

http://www.railpictures.net/viewreje...&key=143860912

I got the bad cropping on the second one right away.

I searched on the forum to see what to do about underexposure, which I read to increase the contrast.

So i take both photos into Picasa (my editing software) increase the contrast on both and cropped the second one, and got the next 2 rejections

http://www.railpictures.net/viewreje...d=625701&key=0

*note I didnt increase the sharpness at all

http://www.railpictures.net/viewreje...key=1265596861

My question is, can they be fixed or save them for the personal files.

Thanks,

Nathan

They are both unlevel especially the 2nd and they do look oversharpened, hmm. The rejection reasons are pretty much spot on.

If something is underexposed, the first thing to try is not contrast but rather exposure. There is a separate rejection for bad contrast.

Also, keep in mind that a screener does not give every possible rejection but one, sometimes two, that are important. You changed the exposure but the sharpening problem was there before and remained. And you really oversharpened - look at the light stripe "halo" along the edge of the lead engine.

Start over with the original image (I am talking about the BNSF 6056) and this time don't apply nearly so much sharpening.

Is there a way to do that with picasa? I click the sharpening button and it does that itself.

does the 6815 not stand a chance?

One way is to go in to the Camera and set the sharping to 0. That way it gets sharped one time.

Picasa: no idea
6815: yes, just change the exposure

Hi Nathan,

In answer to your most basic question, I think these pictures should both be salvageable. The key questions are:

- Do you have original copies of your images? (Hopefully, yes.)

- How much control do you have with your editing software?

One of the later rejections you received was for image quality...too much compression. This is often caused by editing and re-editing JPEG files, especially ones that used high compression ratios to start with. I shoot JPEGs myself and one thing I've learned is that I do all my editing in one session and SAVE ONCE.....well, actually a couple of times if you count resizing and resharpening for RP. If the shot gets rejected, I go get a fresh copy of the image, right out of the camera, and start over. You should always save your original images. Any editing should be done on copies. Also, I keep a notebook detailing the editing I do on each shot. That way, I can go back and recreate what I did if I mess something up.

With respect to your software and the sharpening issue... Been there, done that. I used to use something called Nikon Picture Project. For sharpening, it had only three levels....Low, Medium and High. The Medium and High settings were usually good for an "Oversharpened" rejection. I finally bit the bullet and bought PhotoShop Elements 6. That gives me MUCH more control over the sharpening issue...and a real-time preview as to what it is doing to my image.

On the level issue that Walter raised... The first shot doesn't look that bad to me, but I haven't put a grid on it to check. The second shot with the Orange BNSF ES44 in the lead could be a bit deceiving, since the train is on a curve and the tracks probably are banked. A slight CCW rotation MAY be helpful here. After all, the banking is probably slight....this is BNSF, not NASCAR!

As for the image of the green SD40 that was underexposed, I agree with JRMDC that contrast would not be the first thing to mess with to fix that. I don't know anything about Picasa, but in PSE 6, I would look at a levels adjustment (the Gamma Slider) or perhaps a combination of brightness and contrast. On that particular shot, the adjustments required would not be that large.

In general, you shouldn't need to make huge changes to a shot if you plan to put it on RP. The more you have to mess with a shot, the greater the probability that fixing one problem will cause another. Yes, I have managed to get some seemingly hopeless shots into RP, but generally, I post the ones that look pretty good coming out of the camera.

Download a software that will decrease most, if not all the grain in the image. Neat Image is a good one, as well as Noise Ninja.

I'd ditch Picassa and get Irfanview.

No, Helicon Filter beats that hands-down for freeware:

I used that most recently until I received Adobe...
