Hi everyone

I want to blow out a few pics and get rid of background elements. I was wondering what would be the best way to do it. Something like this pic
Copyrighted_Image_Reuse_Prohibited_800636.jpg

I have some pictures of some BMX tricksters airborne and want to get rid of the backgrounds.

For example this one 819299.jpg

How would I whiten everything so its just the rider airborne ??? Without blowing out the rider ???

Any ideas ???

Is there a way in photoshop to make this happen ? Anyone have a step by step ? PS is not my strong suit :)

This will come naturally if you have light background. Just manually meter off the dark object. 40D should be able to spot-meter, but you can experiment with manual settings to achieve the correct exposure on the object of interest.
For those BMXers, you'll need to get low to put the sky in the background, otherwise photoshop is your last and only resort to whiten the background. Especially with the white shirt that guy wears on your photo...

not much help, eh?

In general, you have to be shooting with the sky (as opposed to the ground in your photo) as the background because it is usually more the few stops brighter. If you expose for the object the sky will usually blow it self out.

In your case you could do it post production with photoshop. Just mask the bike off and paint the background white or some jazz. PS is not my strong suit.

Yes sorry I forgot to convey i wanted to do this in post processing. Would the extraction tool in photoshop work in this type of situation.

Layer mask is your friend. This will help you achieve what you want in a nondestructive manner. Of course, we are talking DPC-illegal stuff now, but you're not planning on using it in a challenge?

Create a curves adjustment layer, with mask. Lighten up everything to your liking. Add mask to your layer. Grab a paintbrush, use the black color, and start painting your cyclist in the layer mask. It will pop back out. Use the black and white colors, different brush softness and opacity and go for the boundary between the fg and bg.

Good luck!

About 3 minutes of work with Play with Pictures. A few more and you can clean out the spokes.
