Peaking Histogram Levels

More
3 years 8 months ago - 3 years 8 months ago #5638 by Ed
Please bear with me as I am a novice photographer.

If my histogram levels are peaking above the chart and I want to lower them but I do
not want to lower the exposure because I am concernced about the white background being
white....

What other settings besides exposure can I look at to bring the histogram levels within the
chart?

Kind regards,

Ed

Can you post a photo of your histogram? Also your white balance is way off. What are your exposure settings? There is quite a lot of noise in there...shouldn't be like that for a studio shot of an inanimate object.

The white balance is set to white florescent (it's a d3200). I have two 400 watt florescent bulbs on a photo tent.

The exposure settings are
aperture f/16
shutter 1/50s
Aperture Priority
Exposure Comp +1.3EV
Metering Center-Weighted
ISO Sensitivity Auto (ISO 3600)

RAW Yes

attached is histogram

Thanks for your help!

I switched from the preset white balance to the mode where you use a photo (I am not sure what is the best photo to use).

Anyway, here is the results I got

Note this is a different color sunglasses from the pair in the original post.

Hi Greg,

I again adjusted the white balance, this time I used the MEASURE method, and the results are a lot better:

This too ;-) is a different color pair of sunglasses.

This explains a lot....
1. turn off auto iso and never turn it on again.
2. when shooting in the studio you should be using manual exposure mode
3. studio photos with inanimate objects I ALWAYS use my minimum iso (200)
4. for this shot your metering mode should be matrix/evaluative
5. also fyi NEVER use exposure compensation with manual exposure mode
6. re: photo tent. I could tell the light was flat and knew it was one of those photo tent things. Throw it in the garbage! I never use them because they make the light so flat and boring.

Mind if use your photo as an example in a video? I'll give you step by step instructions on how to get a great studio shot like this.

White balance is fine, exposure is under by about 1 stop. Try again with the recommended settings, pushing your histo to the right more.

Hi Greg, I really have appreciated your youtube videos BTW, I don't mind if you use the photo(s); but I would prefer if you did not mention my name in a youtube video. Thanks.

f/16 is too much, don't go beyond f/11 unless its necessary.
I'm with greg. In the studio you need manual control over camera and flash to get it perfect. You have all the time in the world to get the shot, why use a mode designed for speed shooting/good 'nuff
Really need to work on lighting to bring it to life. Your lighting is the most important thing here.

Also, see that giant hump on the right of the histogram. That is your white background. It's ok to clip that to the right because your more worried about getting more detail in the glasses. if you look at the rest of the info on that histogram (what left is the glasses), its pretty far left and not optimally exposed. Also since you are shooting raw, you can salvage things clipped by quite a bit.
