Check out these photos captured in Wuquanshan Park in Lanzhou, Gansu, China by photographer Adam Rainoff arainoffphoto , with the help of our WonderPana 145mm Circular Polarizer Filter. Adam shot these images with his Pentax K-1 and Pentax-D FA 15-30mm f/2.8 lens, plus our Tamron 15-30 WonderPana filter system, which actually fits on the Pentax lens. Adam says that "The polarizer filter helped me increase the contrast, punch out the colors, and reduce the glare of the midday sun." - #WonderPana #LandscapePhotography #China #Filter #PhotoFilter #CPL #PentaxK1 #Pentax15to30mm #architecture #park #AdamRainoff #travelphotography #polarizer #WuquanshanPark #Lanzhou #Gansu #CPLFilter #UltraWideAngle
