Does anyone have a good morph face swap tutorial that they followed when they first got started? Mine are looking terrible so far

Let your first step do most of the heavy lifting and find a face that matches the angle of the face you’re replacing. no editing can fix a face pointing the wrong direction. Cut out the face leaving some area around it (hair, neck, etc) and paste it on top of the old face. Adjust the size to match (bigger or smaller) and if you can make it transparent when resizing, try to line the old and new eyes up and adjust the head’s tilt by rotating. Then use an eraser with feathered edges as opposed to a hard edge, and start lightly erasing the extra area I said to leave in. You can fade the hair and blend the skin with the soft edge eraser. That is basically it but if you want to do more, adjust color levels, brightness, saturation, etc. to match skin tones.

Do you have any suggestions on how to morph a pregnant belly on as well?

Just want to preface that not everyone has the same style in morphing and not everyone wants the same outcome. For me, I like it as realistic as possible, including not doing hyper-preg. That being said:

As I said with the face, you’ll get the best results shopping for the right pictures first, then starting your editing. I start with the body then find a belly to match. For the body, I use one that has a decent resolution, is well lit, is free of obstructions (like other body parts or shadows), and is in a good pose to add a belly to. For the belly, I would suggest going onto imagefap or similar website that has a good amount of high quality photo galleries of pregnant women. Usually one gallery set alone can have many usable bellies in all the different angles to match the angle of your body. You only need to focus on the angle as we will edit the rest, so look for a pregnant woman in a similar pose to the body you’re adding a belly to. Once you have body and belly in your editing software (I use pixlr), you need to cut out the belly. It can be crude and you you want to keep from above boobs down to pubic line or the whole vagina if you are using that too. Copy and paste belly onto your body and first resize so that the belly is in proportion to the body. Twist the belly around the central axis to adjust it’s rotation to match. You can line up nipples or other body feature if you can make the belly transparent when doing so. Once the right size and angle, it’s time to really start the magic. I start with the feather eraser and give it a deep feathered edge (softness). Clicking close to but not on the belly, you can take fine erasures away and blend it into the body and remove the harsh edges from the paste. Leave whatever body parts you like, erase the rest. Next you need to adjust the skin tones to match. I color sample to belly and write down the RGB values as well as the hue, brightness, and saturation. Do the same color sample to the body. Do some addition or subtraction and write down the difference in numbers for all 6 values. On the belly layer, adjust those 6 values in the amount of the math you just did. The RGB should be pretty good, the other three might need fine tuning or you might find using hue isn’t helpful at all. That’s the basics but happy to elaborate.
