Crobato, you know there are too many fake pix of PLA on the Chinese forums, that makes me careful before I decide to believe any new pix. Though this one was given high credibility, I think we better be patient, and wait a little more before we draw any conclusion. Personally, I really don't like the DSI installed J10 (in the pix), it looks weird. IRST is great and I also hope they can get a more powerful engine, some 150KN thrust for example, even though this is hard.
A few minutes later:
I copied this from sina.com. Somebody concluded that it is a PSed. It generally said:
1. The speed measure tube is too big
2. The pennant number looks modified
3. Inlet has different color with the body
4. The canopy has a white spot which shouldn't appear in the weather condition of the pix
5. The rear part of the missile looks pale which is not consistent with the whole aircraft
6. The most serious mistake is the scale of people stand near by the aircraft. That bird looks too big?
it looks pretty real to me. but if it is fake, the perpetrator is pretty damn good.
the white spot on the canopy cant be a helmet its too big to be a helmet.
and i dont know if those things next to the landing gear are people, but the white spot is definitely too small compared to the "body" to be a helmet. so assume that the person was bending over for reasons we do not wanna know, then the scale is correct.
the most important thing is, if this is PSed then there must be an original version flowing around on the internet somewhere, the body hasnt been painted which means it might be going through some kind of a test or something, which means that you prolly cant just take a camera, take the photo and then PS it on your computer.
ps. in the second set of photos posted by crobato, we see that dome thing behind the canopy was gone, but in the first set of photos it was still there. now assume that all of the four photos were "PSed" by the same person, i think it was took obvious for him not to notice that. but then again you can also used that to discredit the photo, works both ways
