I like to seek opinion on whether the skintones are too yellowish. They actually look ok to me. Hope i do not need to calibarate my eyes
If I'm not wrong, your 1st pic is shot using the 50mm f1.8...If u are shooting portrait that will literally fill up your screen (eg half-body or neck-to-face shoot) and u are using "Single point" or "Dynamic area" on AF-area mode, as well u are using "Normal zone" on "Center focus point" mode, then be careful that your "Center-weighted area" do not set too small (eg. 6mm diameter) else your subject of the four corner will be blur.
To overcome this, set your "Center-weighted area" to 10mm diameter under the "Metering/exposure" control custom setting...this will tell the camera to have a more wider area of center-focus point (vs 6mm diameter where center-focus area is smaller, hence subject of the four corner will be blur).
Are u using pop-up flash with "orange" diffuser?
One way to test your surrounding exposure against human skin-tone is to set your Picture Control to "Neutral", Image quality to "Fine", Active D-Lighting to "Off", Color space to "sRGB", Whilte Balance to "4170 K"(under Choose color temp.).
All these parameters can be set under "Shooting Menu". White Balance "4170 K" will give u the normal lighting skin-tone that we see with our eyes...however, this setting must compliment with rest of the parameters setting mention above.
If u find the surrounding exposure having too much amber lighting, using the White Balance "4170 K" as a bendmark, u can tone down the color by reducing the White Balance "K" to 3700 K or 3570 K,etc. Basically, the lower the value of the White Balance is the cooler the skin-tone will be...subsequently the higher the value of the White Balance the "warmer" or more yellowish/orange the skin-tone will be.
If u are using flashgun or pop-up flash, set your White Balance no less than "5000 K" value.
Hope this help...
Thank you alot guys for the tips and advice
