them, but they are still suffering from some ghosting issues.

not being particularly picky or careful.

What I'm doing with this process is just clueing Photomatix into where the

ghosting problem is.

When I do that, Photomatix now knows this is an area it needs to consider for deghosting. 
当我这样做,Photomatix现在知道这是一个区域deghosting需要考虑的。

53
00:02:59,820 --> 00:03:04,190 
Now I could go ahead and circle the other two and head off to do my final processing, 
现在我可以继续绕着其他两个,去做我最后的处理,

54

in to try and get a better view.

often they come out of the merging process very dark.

基本上这是做什么,是做正常HDR合并过程

98 
00:05:24,580 --> 00:05:28,560 
taking that extra deghosted stuff and layering that back on, blending it

我们放大,果然,看那里。他没有

have a noise problem.

我可以照顾,在后期处理。我就不担心了。

这是放大很接近,所以我不会过于担心是否

110 
00:06:03,440 --> 00:06:07,360 
that noise is even a problem until I do a print and see if it actually is an

can see how much you can correct it. 
可以看到有多少你可以纠正它。
