I create a new layer. I used gradient tool( black color) to make a gradient on the picture. I also used overlay on that gradient. I place it at top left and bottom right of the picture.

I placed these images in a suitable position.

I used lasso tool to cut out the war tank from the original picture. i applied feather, opacity and fill on the tank. I do play some brightness on it. I desaturated it and placed it in the middle.

The above image is i copy from war scene picture. I again used lasso tool and feather to paste on the photoshop. i desaturated it and applied some brightness. i combined this image with the death body image together.

I download this two victim picture and i used lasso tool to cut it over to Photoshop.
I apply feather,opacity and fill on it. I play on desaturated to make it black and white color.
i do play on the brightness too...
I combined the both picture together to make it become one image.

This is a death body and building images which i copy from a war scene2 picture. i used the same tool , lasso tool, desaturated, opacity and fill, feather and i do apply some brightness on it.

I copied and pasted again from original picture. As the same as the aircraft, i used lasso tool, feather and some opacity and fill on the picture. I play on the desaturated tool too.
