I use
PSP X & XI, your little bug photo has a yellow cast. I tried curves and levels but didn't get the results I expected it could have been the photo's themselves.
* Make the photo Active
* Image -> Split Channel -> Split to HSL
* Copy the L Channel and then delete all 3 channels
* Make photo active and split to RGB
Image ->Split Channel-> Split to RGB
*Select the Blue Channel do CTRL+A (you should now have the marching ants)
* Right click on the photo and select PASTE INTO SELECTION then CTRL+D (To get rid of the marching ants) THEN
* Image -> Combine Image -> Combine RGB
Do both photos and run a color balance.
That's what I did to get the results attached.
