Photographer, know thy camera!
We know we should not take pictures with important highlights clipped from our precious photos. This is why our cameras show histograms and flashing pixels in the LCD, but… are they always right?
I was taking photos of wildflowers and I noticed there were flashing pixels in the whitish sepals when making what I thought was the right exposure. I knew that cameras calculate the histogram and the overexposure warnings from the in-camera jpegs (or from the jpeg preview embedded into the raw files) and would not be accurate, but I decided not to take chances and decreased my exposure until the highlight clipping was gone.
Camera-produced jpegs are processed to show good midtones (where our main subject normally is) and forget about deep shadows and highlights if needed by the quick internal decisions taken by the camera’s computer.
Back home I looked at the photos and yes, the highlights were clipped in the jpeg files… but the raw files looked just fine (I shoot raw + jpeg). Luckily I didn’t delete my “overexposed” photos in the field!


This is not a new lesson for me, but I certainly learned an important one when I tried to fix the “underexposed” photos in Lightroom just to see… They looked flat, grainy and lacking detail in the shadows. I looked to the exposure compensation needed and it was over two stops! No wonder they looked bad.

We hear a lot about not to clip the highlights (these are the important, textured highlights, not the light sources or their reflections), but we should know what our camera display tells us and decide whether we should pay attention to the warnings or not.
I wonder if all cameras behave in the same way. Does yours?
En mi opinión lo mejor es definir que es lo mas importante a la hora de hacer la exposición y previsualizar cómo queremos nuestra imagen resultante. Bien hecho tocayo!
