(URGENT x 2) : how to stop items blur while other image is mouse-over stated

Dear Sirs,

My client wish to change the Ablum items effect urgently

When there is an item (photo) being mouse-over, other image will sudden turn blur as attached image. 

My client Do hope there is some method to STOP this effect immediately as she feel very unwell to see this effect 

and also how to allow user click to pop up  (modal) an item (photo), we cannot found any setting yet.

Thank indeed for your kind attention.

Thanks
