Lens: Canon EF-S 55~250mm, IS, STM Lens Camera: Canon EOS 7D Mark II Photo Location: Sherwood Forest ISO: 250 Shutter Speed: 1/125s Aperture: F7.1. Manual Exposure Mode with Multi-Segment Metering. Thanks very much for viewing. Tony
Lovely looking flower, very upside down appearance. Just a tip with red flowers. Try using Spot Metering and drop the exposure a stop. The red channel will always clip when the scene is filled with red so to reduce that always shoot RAW.
Hi Tony. Clipping occurs when you overexpose the shot, commonly known as "Blown Out" highlights. It also happens in the RGB elements. This can happen in a red flower shot where the red is blown and the green and blue channels are not effected. Most cameras are able to show the RGB histogram when you play back your image. When you view the image on the LCD screen, press the "Info" button until you see the histogram. This will show blown out highlights. To see the RGB histogram, set it up as below from the menu system. With "Highlight Alert" ON you will see the "Blinkies" when you view your image on the LCD screen. The blinkies are showing the blown out parts of the image, which, on the histogram, will show a spike on the right hand side. Although the Red Histogram shows no clipping, the reds can have a lack of detail. This is a common problem with today's digital sensors. To overcome this, always decrease exposure so you keep the detail and always shoot RAW. On your image above the histogram is not showing blown out highlights BUT parts of the RED are showing as MAGENTA which is a sign of slight overexposure in the red channel (but not clipped), but there are tricks to correct it in post. I can't remember what software you use, so if you let me know that, I may be able to show you how to fix it. I hope some of this makes sense
