Another attempt at some studio work. Taken with my camera on a tripod and placed the batteries inform of a white background. I used a levels adjustment layer and also a threshold layer to change the background to as white as possible as it came out a little grey when i tok the shot. Any suggestions?

It is what it is - a perfectly executed 'product' shot. This is catalogue stuff with room for logos, prices etc.

Hi Andy.

Without knowing your exact setup it's a bit of a guess but your exif info says that your flash did not fire so therefore you must have used other lighting to create the exposure. Due to the nature of the shadows cast by your subjects I am assuming that it was an overhead light in the room that you used.

Did the subjects come out slightly underexposed also? If so then it would probably be a case of just dialing in a stop or two of negative exposure compensation as your cameras meter would have been fooled by the white background and tried to expose the scene as a mid grey. This should render the background more white and hopefully expose your main subject properly.

If your subjects were exposed correctly then it may be just a case of using a reflector to bounce more light into the background so it is properly exposed as white or you could use a desk lamp to light the background and diffuse the light with tracing paper or some baking paper. This can be tricky as you will also have to make sure the extra light will not fall on the main subject which could leave it over exposed.

Eitherway, getting the main subject and the background exposed correctly in camera will leave you with the maximum amount of detail to work with during post processing.

Yes he used studio lighting and in exif studio lights do not tend to come up as flash firing.
Not sure what you want us to critique, all i can say is well done on a good job.

A desk lamp to expose the background would not work, for one it would be a different light to the studio lights and therefore mess with the cameras white balance.
However you are nearly there all you need to get the back ground nice and white is one stop more exposure on the light facing the background and one light facing the subject correctly exposed, this works well for me with people and i get a nice high key look.
Also use the grey card for custom white balance it will make your colours really pop and add to the white being white as it should be.

just done a mod for you in cs5.
I tweaked the colour balance to where it should be which made the colour pop more and the white becomes whiter plus tweaked the sharpness a tad too.
other than those tweaks i would say you got it all wrapped up there.

For your information I didn't use any lighting at all. I took the photo in my conservatory so had lots of natural lights flooding in. I placed my subjects against the directness the light was coming from to reduce the shadows. The background was Grey whine I started post production and the batteries were slightly under exposed. So I will try and use your over exposure idea today and see what happens.

That's good to hear Andy. From the look of the shadow under the batteries I thought you may have used an indoor setup with the overhead room lighting so that's why I suggested using a desk lamp to light the background as the two would be tungsten and compatible but Ian is quite correct in saying that it is a different white balance than studio lighting.

Also it is worth noting that setting a white balance in camera can give slightly different results than the same setting in camera raw editor. I set the sunlight setting on my D70 for a recent photo but the same setting in camera raw made the photo slightly more vibrant. This shows slight differences between the camera manufacturers white balance settings and Adobes.

As Ian's modification shows it is worth experimenting.

many thanks for that. Yes i think Ian's Mod is really good. It has the extra colour pop of white that i am trying to get. back to the drawing board and going to practise getting that extra brightness again!

Ian, just out of interest when you tweaked the colour settings in the colour adjustment layer what settings did you put in?
