Hi,
Did it capture the milky way?? Can't really see it in the image.

Anyway, I think 15 second is a little too short to capture the milky way... try a longer exposure or use a higher ISO setting and also use the raw mode to store the image.... The jpeg sometime will "kill" those faint milky way image during the compression process.

By the way, those nice milky way image is normally the result of very long exposure.

Have a nice day.

15 sec not possible to capture milky way ....those you capture there is the main constellation of sagi and scorpius.

At 15 sec, there is very little you can do with photoshop. Maybe you can try to increase brightness or contrast to see if that brings the stars out a little more.

Photoshop is only useful if you do stacking.

Anyway, just to comment, i.m.o. I think that it's not easy to use Photoshop to work with images with so little contrast. For any image, in general the higher the contrast of the picture, the easier it will be to work with the image. That's because when the contrast is higher, the boundaries of objects in the image will be clearer, and thus you can edit them more easily. Filters will work better too, as their effects can be more easily seen.
