Highpass filter like Photoshop

Does anybody know algorithm similar to Photoshop High Pass filter? I'm using this one. But it looks different and just "cut" low signal and i want to leave only high and low signals without middle.

I know that i should to use convolution, but actually i don't know how to do that properly.

Any suggestions?

Maybe just take mean value of sum of highpass and lowpass filters outputs. It will give You combination of low and high frequency in very easy way. Matlab-like pseudocode below:

img_low = low_pass(img)
img_hight = high_pass(img)
img_lo_hi = (img_low + img_high) / 2
