Dongdong traveled to Finland with her parents and they took many photos. After returning home, Dongdong first puts all the photos with her own portrait into her own photo album, then puts the remaining photos with her mother's portrait into her mother's photo album, and finally puts the rest of her photos into her father's photo album , Dad thinks that all the photos with his own portrait should be put in his album, so he took out a total of 37 photos from Dongdong and Mom's album and put them in his album. Mom disagreed, and put them in Dongdong All 45 photos of myself in the photo album with my father were taken out and put in my photo album. I would like to ask: Is it because the mother and Dongdong take more photos together, or the father and Dongdong take more photos together? How many more?
冬冬和爸爸妈妈去芬兰旅游，他们照了很多照片．回家后，冬冬先把所有有自己像的照片放到自己的相册里，再把剩下的有妈妈像的照片放到妈妈的相册里，最后把剩下的照片放到爸爸的相册里，爸爸认为应该把所有有自己像的照片都放到自己相册里，于是从冬冬和妈妈的相册里一共拿出了37张照片放到了自己的相册，妈妈不同意，又把放在冬冬和爸爸的相册里所有有自己像的45张照片都拿出来放到了自己的相册．请问：究竟是妈妈和冬冬的合影多，还是爸爸和冬冬的合影多？多几张？
