Is physical mediumship fraudulent?

I'm strongly inclined to believe they are fraud:

1) I believe the pictures are 'photoshopped' due to the abnomalies I have highlighted. Sven Turck was a photographer by living.

Even though the second of those so-called anomalies was utterly ludicrous? And the first had a quite ordinary explanation.    Perhaps you don't realise how foolish this makes you sound?

Yes, he was a photographer who produced work of an extraordinarily high quality. Well worth a look simply on the basis of the photography itself.

2) The pictures are taken in his own home 

That would be convenient for arranging the camera and lighting. Most likely he often used parts of his home for photography, or maybe it was adjacent to his studio. Certainly there are many family scenes and festive occasions among his work, again of very high quality.

3) At least one well-known medium-fraud Anna Melloni attended his seances even though she isn't  present on these particular pictures

From the huge quantity of high quality images available online, his work covered many and  varied areas,  presenting a time-capsule of everyday life in its many forms during that era. People at work, people at play, street scenes, landscapes, architecture interior and exterior. Whatever he captured seems to fall within that remit - a slice of everyday life.
