Use Photoshop and a new layer over it and reduce the opacity. That is the best method!

How do I submit images revised at only 600 Pixels max. You can't see details in my colorized work at only 600 pixels max.

[You've misread the Submit Image instructions; note that the "600" figure refers to the file size in kilobytes, not the image dimensions, and that itself is just a suggestion. The recommended minimum image dimension is 1000 to 1200 pixels wide, although we regularly accept colorized photos as large as 2000 pixels wide.]

[Thank you for the response. Will keep in mind next time.]

Thanks for the responses, guys. I use CS5. Yes, I grew up around TN waters and most are dingy olive green. The main difficulty I run into when converting to color is the intensity of the colors applied. Do I Multiply the color layer, do I Overlay, or do I simply covert to Colorized monotone. It's interesting to see the results from each.

Blackxacto,
What type of software are you using when colorizing? I use Photoshop and my practice in your picture would be to add a blank layer over the earth layer, select a soft brush and a darker tone in the same color range then paint-in the darker shaded areas. Adjusting the "opacity" settings will also change the results too, you have to play with the settings a bit to suit your imagined color.
Nice work and I hope that this is of some help. Don

Nice work.

Depends what programme you use (I use Photoshop myself) but you could try reducing the saturation further to a more grey-brown tone, or alternatively (or as well) put down a base-layer of that colour and then brush over some areas with a low opacity feathered brush of a slightly different tone. The vertical "cliffs" could have a slightly more yellow-grey tone.

I like the river colour, as the temptation is to use blue, but the green looks far more natural.
